Best Hydration Pack for Obstacle Course Racing of 2026 Top Picks

The Nathan QuickStart 3.0 Hydration Pack is a minimalist 4-liter trail vest engineered for fast-and-light day hiking, trail running, fastpacking, and warm-weather outdoor adventures. Built for outdoor enthusiasts who want easy access to fluids without carrying a cumbersome daypack, this vest bridges the gap between an endurance harness and an everyday trail pack. It is well suited for solo adventurers, weekend warriors, day hikers, festival goers, and active campers who frequent technical ridgelines, desert tracks, and wooded state park loops.

Hydration management on the trail is simple and adaptable. The harness comes equipped with two 14-ounce soft flasks positioned in tiered front chest pockets, allowing quick sips through smooth push-pull bite valves. Because these flasks compress as you empty them, fluid slosh is kept to a minimum. For hotter desert treks or remote backcountry routes requiring extra water capacity, the main rear pocket features an internal bladder sleeve with hook-and-loop keepers that holds a separate hydration reservoir. Moisture-wicking air mesh panels on the harness straps and back panel ensure steady ventilation across strenuous ascents.

Built from a resilient blend of polyester, nylon, and flexible spandex, the outer shell handles abrasive contact with rough brush and granite boulders while drying quickly after sudden mountain rain showers. The front harness integrates expandable power mesh pockets that keep energy bars, lip balm, and navigation devices within easy reach. To eliminate pack bounce on uneven terrain, wide side straps pull the lower harness flush against the ribs, while elastic keepers secure loose webbing so straps do not flap around in windy conditions.

Despite weighing only 7.45 ounces without water, the pack supplies 244 cubic inches of practical storage space. The rear expandable compartment holds a packable windbreaker, light rain shell, compact first aid kit, headlamp for navigating camp after twilight, and a multi-tool. Its slim profile also makes it convenient to pack flat inside a larger duffel bag or expedition backpack, serving as a ready-to-go scouting pack once basecamp is established.

There are a few trade-offs inherent to its ultralight focus. The 4-liter total capacity cannot hold heavy camp cookware, bulky down jackets, or standard shelter equipment, making it strictly a companion for daytime excursions. Furthermore, the one-size-fits-most chassis relies on sliding sternum cords and side webbing, which may require careful adjustment to dial in a snug fit across different torso shapes. The bite valves and flexible flasks also demand routine cleaning and air drying to maintain optimal hygiene.

For hikers, trail runners, and day adventurers seeking a dependable, ergonomic hydration system that frees up their hands, the Nathan QuickStart 3.0 is a strong, comfortable choice. Backed by a lifetime warranty, it delivers dependable airflow, versatile fluid carriage, and practical storage for long days spent exploring the outdoors.

Weighing only 7.45 ounces empty and 12.41 ounces with both empty flasks inserted, this vest keeps weight to an absolute minimum on steep mountain climbs. The pliable fabric structure folds virtually flat, making it easy to store in a camp bin, vehicle console, or family camper van.

For multi-day backpackers, this pack rolls up neatly inside a full-size trekking rucksack, allowing you to drop heavy basecamp gear and carry just water, snacks, and a shell on side excursions to distant peaks.

The included dual 14-ounce soft flasks sit securely in the upper harness sleeves, positioning drinking valves right below chin level to make hydration effortless without slowing your hiking cadence. Their soft walls collapse downward as you drink to stop fluids from bouncing against your ribs.

When water access is scarce, the rear compartment easily houses an auxiliary hydration bladder, providing the fluid capacity necessary for extended outings under intense summer sun.

The MIYCOO 10L Hydration Backpack is an ultralight daypack engineered specifically for staying hydrated during active outdoor pursuits. Equipped with an included 2-liter reservoir, this pack caters directly to day hikers, trail runners, mountain bikers, weekend warriors, and music festival goers. Budget-conscious adventurers and first-time campers who need a reliable, self-contained water delivery system without hauling bulky bottles will appreciate its streamlined design. It fits neatly into car camping kits, gear closets, and emergency preparedness totes for quick outdoor getaways.

Staying hydrated on a steep summit push or during hot afternoon festival walking requires quick fluid access and minimal bounce. The pack utilizes breathable mesh shoulder straps integrated with flexible silica gel elements to disperse weight evenly across the collarbones. This open-weave harness aids continuous airflow, which helps reduce sweaty hot spots on long, warm trail stretches. The 10-liter interior capacity supplies just enough cargo room to pack trail mix, a headlamp, sunglasses, keys, and an ultralight windbreaker. An external elastic bungee network stretches across the front face, letting hikers lash down an extra layer or a quick-dry camp towel on the fly.

The centerpiece of this pack is its 2-liter food-grade, BPA-free hydration bladder housed inside an insulated internal sleeve. Based on product specifications, this thermal barrier helps maintain cold water temperatures for up to four hours, which makes a noticeable difference when hiking across exposed slickrock or under scorching summer sun. The bladder features a wide mouth for straightforward filling and ice cube loading, as well as a thickened seam construction to safeguard against sudden leaks inside the cargo hold. A secure hose connection routes effortlessly to the shoulder strap for consistent drinking on the move.

Built from durable woven polyester fabric, the backpack stands up to brush scrapes, picnic table scuffs, and dusty festival grounds. While it lacks heavy-duty technical features like internal aluminum stays or extreme ripstop nylon, its lightweight construction keeps trail weight low so hikers can move quickly. Standard smooth-gliding zippers secure the front utility pocket, bladder slot, and main storage chamber. A 1-year manufacturer warranty offers added peace of mind for seasonal campers looking for dependable value.

While this pack excels at high-mobility day trips and casual outings, it is not built for extended multi-day backpacking trips where bulky sleeping gear and freeze-dried meals must fit inside. Additionally, the fabric provides basic splash resistance, but hikers facing relentless downpours will want to bag sensitive electronics or pack a separate waterproof rain cover. For trail runners, day hikers, festival campers, and casual outdoorsmen seeking an affordable, grab-and-go water solution that keeps drinks cold on sunny trails, the MIYCOO pack delivers exceptional utility and everyday trail convenience.

The insulated bladder compartment is lined with a reflective thermal material that helps shield your water supply from ambient body heat and direct sun exposure. Dropping standard ice cubes through the wide-mouth bladder opening enhances cold retention, keeping your sips crisp during warm mid-day ascents.

Offering 10 liters of total storage, the backpack balances compact agility with practical organization. Three zippered compartments allow you to separate damp trail gear from your smartphone, keys, and snacks, while the exterior bungee cords secure bulkier apparel without opening the pack.

To keep the 2-liter water bladder clean and fresh after each hike, rinse the interior thoroughly with warm water and mild dish soap. Avoid harsh detergents or boiling water that could degrade the food-grade plastic or silicone seals.

Air drying is essential to prevent moisture buildup and odors. Prop the bladder open using a kitchen utensil or dedicated drying rack, and hang the drinking tube vertically so all residual droplets drain completely before storing the pack in a cool, dry place.

The Fox Racing Utility Hydration Pack is an ultra-compact hydration daypack engineered for active outdoor recreation where agility and quick hydration access matter most. Designed with a streamlined 6-liter gear volume and an included 2-liter HydraPak reservoir, this pack caters to day hikers, fastpackers, mountain bikers, trail runners, and festival campers who prefer traveling light. Whether you are trekking along sun-drenched canyon trails, exploring state park loops, or walking around crowded outdoor festivals, this low-profile carrier delivers essential hydration without unnecessary weight.

Regarding hydration performance, the integrated 2-liter HydraPak reservoir provides ample capacity for moderate half-day adventures and hot afternoon outings. The bladder system provides a clean, neutral taste and pairs with a responsive drink hose that delivers consistent flow. A key functional highlight is the magnetic hose retention clip, which snaps the drinking valve firmly back onto the chest strap after taking a drink. This prevents the hose from flapping around or dragging through dirt and brush when descending steep trails or navigating rocky scrambles.

Fox Racing constructed the Utility pack with tough polyester fabric capable of withstanding rough woodland trails, dusty fire roads, and brushy terrain. The interior layout is efficient, featuring a dedicated fleece-lined compartment that safeguards sensitive optics, smartphone screens, or compact cameras from trail grit and scratches. A built-in internal key clip prevents your campsite car keys from sinking to the bottom, while tactical MOLLE webbing across the front exterior offers convenient anchor points for securing carabiners, compact multi-tools, or a trail headlamp.

Comfort on the move is supported by a body-hugging harness layout that keeps the load centered along your spine to prevent shifting on uneven surfaces. The harness straps allow natural upper-body movement, making it easy to climb steep inclines without feeling restricted. Maintenance is straightforward as well, since the HydraPak bladder removes easily for thorough washing, rinsing, and drying between weekend excursions. The entire pack also compresses flat, making it effortless to stow inside a larger family camping duffel or a crammed car trunk.

While the compact 6-liter capacity is not designed for all-day alpine treks that require bulky weather protection, extra rations, or camp cooking gear, it excels at focused short-duration trips. For solo adventurers, mountain trail enthusiasts, and active day hikers seeking a durable, bounce-free water reservoir pack, the Fox Racing Utility Hydration Pack provides a practical and well-built trail companion.

The integrated 2-liter HydraPak reservoir provides sufficient water volume for typical two to four hour day hikes depending on temperature and trail exertion. The bladder is crafted with durable, flexible materials that hold up well to pressure inside a loaded pack, while the wide-opening top allows for easy refilling at campground water spigots and backcountry filter stations.

With 6 liters of designated gear capacity, the pack encourages disciplined packing. It easily accommodates energy bars, a compact first aid kit, tire levers or a pocket knife, and a lightweight windbreaker. The magnetic retention system ensures your drink valve remains within instant reach at your chest, preventing distractions when moving quickly across technical outdoor terrain.

Built using abrasion-resistant polyester, the pack exterior is prepared to handle encounters with rough bark, low branches, and dusty trail conditions. Reinforced stitching across the shoulder strap anchors and haul handle helps maintain structural integrity under continuous movement.

The external MOLLE ladder webbing expands storage versatility by letting you clip on extra items like a compass pouch, bear bell, or small utility pouch. To preserve the pack and hydration reservoir over time, rinse the bladder with mild soap and warm water after each outing and allow both the bag and reservoir to dry completely in a shaded, well-ventilated area before long-term storage.

The Fly Racing XC Hydro Pack is a streamlined, purpose-built hydration daypack engineered for high-output outdoor activities. Originally created with off-road powersports and cycling in mind, this compact pack transfers effortlessly to trail hiking, fastpacking, festival grounds, and day trips away from basecamp. At just one pound empty, it focuses strictly on core hydration delivery and small essential storage, making it ideal for minimalist hikers, solo adventurers, mountain bikers, and car campers venturing out on quick excursions.

Hydration performance centers on the included 1-liter (30 fluid ounce) HydraPak Elite reservoir. The reservoir features a wide slide-top opening that makes refilling from campsite spigots or backcountry gravity filters hassle-free. Thanks to the integrated Plug-N-Play quick disconnect system, you can pull the reservoir out for a refill without unthreading the drink hose from the pack strap. On the trail, the high-flow Blaster bite valve opens with minimal effort, self-seals automatically after each sip, and includes an intuitive twist lockout to eliminate annoying dribbles against your shirt or camp gear.

Fit and torso stability stand out as key strengths of the harness design. The chest harness relies on elastic Velcro bands that adjust dynamically with your body as you hike uphill or pedal over rough singletrack. Side strap fine-tuning attachments allow the pack to accommodate smaller body frames comfortably without shifting or chafing. Additionally, the main harness hardware uses oversized quick-release buckles that unclip effortlessly, even when your hands are cold or wrapped in thick camp work gloves.

Storage options are compact yet thoughtfully arranged for short outings. The main compartment holds the water bladder alongside two internal sleeve organizers that fit pocket knives, compact first aid supplies, or headlamps. On the outside, an exterior zippered pocket handles smaller loose items like keys or trail snacks, while a stowable mesh flap pulls out to hold a light rain shell or pair of gloves. Reflective zippers and branding provide helpful extra visibility when trekking back to the campfire after the sun goes down.

Maintaining the hydration setup is simple enough for casual weekend use. Because the HydraPak bladder turns inside out, drying and scrubbing the interior between camping trips takes only a few minutes, reducing the risk of mold buildup. The main limitation is overall fluid and gear volume. A 1-liter capacity is insufficient for all-day desert treks or dry camping trips without water sources, meaning extended outings will require packing additional water bottles or filtration gear.

For outdoor enthusiasts who want a lightweight, durable hydration rig that will not bounce around on active trails, the Fly Racing XC Hydro Pack offers dependable performance. It serves as a reliable hydration companion for short summer hikes, festival weekends, mountain bike loops, and quick day treks from your camper or family tent.

The core of this pack is its HydraPak Elite 1-liter reservoir, manufactured from durable, BPA and PVC free materials. The wide slide-top opening creates a tight, dependable seal while allowing you to easily toss in ice cubes before leaving the campground cooler. It also makes washing out drink mix residue much simpler compared to traditional narrow screw caps.

Trail usability is enhanced by the Plug-N-Play tube coupling. You can disconnect the bladder with a simple push button while the hose remains threaded through your shoulder harness. Paired with the self-sealing Blaster valve and positive twist shutoff, this system keeps your water secure and accessible on demanding trail routes.

Unlike standard daypack straps that can slip during vigorous movement, the XC Hydro Pack employs a secure chest harness system. Integrated elastic bands provide enough give to let your chest expand fully while breathing heavily on steep climbs, yet keep the pack pulled tight against your upper back to stop side-to-side sloshing.

The harness includes fine-tuning strap anchors along the sides, making it easy to adapt the pack for smaller builds or layered cold-weather hiking apparel. Large quick-release buckles provide smooth entry and exit without fumbling, which is especially convenient when wearing damp or insulated trail gloves.

The CamelBak Mil-Tac HydroBak is a hydration pack built for action. Designed for minimalist use, it carries 1.5 liters (50 ounces) of water in a slim, stable reservoir that fits close to your back. This pack is best suited for cyclists, runners, hikers, and others who want to stay hydrated without extra bulk. It also works well for day hikers, festival goers, and commuters who need a light carry.

Real-world performance centers on comfort and ease. The diamond mesh back panel and lightweight harness provide excellent air circulation, reducing sweat buildup on warm days. The Antidote reservoir features a low-profile design that stays put even during off-road biking or trail running. The patented Big Bite Valve delivers water on demand with just a bite and sip, while the air-lean fillport cuts down weight. The reservoir includes HydroGuard technology to inhibit bacterial growth, making it safe for regular use.

Build quality is solid. The outer pack uses 70D Diamond Clarus with DWR coating and 1000mm PU coating on the front, and 210D nylon with 400mm PU coating on the back. This combination resists light rain and abrasion from rocks or brush. The quick-release shoulder straps unclip easily, letting you remove the pack without taking off your helmet. The external zip pocket is just big enough for a multi-tool, wallet, or keys - but not a large phone.

Setup and use are straightforward. Fill the reservoir through the wide-mouth opening, tighten the quick-seal cap with a quarter turn, and you are ready. Cleaning is simple with the big opening, and the reservoir can be stored dry to avoid mold. The pack has no frame or extra pockets, so packing is limited but intentional.

A realistic limitation is capacity. At 1.5 liters, this pack is best for short outings of up to 90 minutes. For longer days, you will need a larger hydration system or a pack with extra water bottles. The pocket is also quite small, so if you carry a modern smartphone with a case, it may not fit. Some users find the shoulder straps a bit thin for heavy loads.

Overall, the CamelBak Mil-Tac HydroBak is a reliable choice for anyone who wants a lightweight, hands-free hydration pack for short, active adventures. It is ideal for mountain bikers, trail runners, minimalist hikers, and commuters. If you need more capacity or storage, look at larger models. But for stripped-down efficiency, this pack delivers.

The CamelBak Hydrobak 50oz is a minimalist hydration pack engineered for streamlined performance during quick outdoor excursions. Built around a 1.5-liter Crux reservoir, this pack caters directly to day hikers, trail runners, mountain bikers, festival campers, and outdoor enthusiasts who prioritize traveling light. Whether you are venturing out on a short loop from basecamp or spending an afternoon navigating a crowded music festival, this compact setup keeps clean water accessible without the heavy footprint of an expedition bag.

Hydration delivery is the core strength of this system. Based on product specifications, the Crux bladder is engineered to supply 20 percent more water per sip compared to standard legacy designs. The ergonomic handle makes refilling at campground water spigots or backcountry filtered pumps quick and straightforward. An integrated leak-proof on/off lever prevents accidental leaks while your pack rides in a vehicle trunk or hangs from a tent gear loft, ensuring that every drop remains ready for the trail.

The pack is constructed from resilient nylon and polyester fabrics designed to withstand snagging tree branches, abrasive dirt, and repetitive trail use. Breathability remains a priority during high-output summer hikes, which is why CamelBak includes an air mesh back panel paired with a ventilated mesh harness. These panels allow consistent airflow across your back and shoulders, helping to manage sweat buildup and prevent chafing during warm afternoon excursions under direct sunlight.

Storage is deliberately pared down to essential items. With a dedicated zippered compartment, campers can safely carry car keys, a compact folding knife, trail ID, or an energy bar. That streamlined profile means there is no room for bulky rain gear or camp stoves, so solo adventurers planning all-day remote backcountry treks will likely need to pair this with a larger daypack or look for higher-capacity luggage. The entire pack weighs under a pound empty, making it an effortless addition inside a larger car camping duffel.

Taking care of the Hydrobak requires standard hydration bladder maintenance, including air drying the reservoir between trips to prevent mildew. The setup is covered by the manufacturer Got Your Bak Lifetime Guarantee, giving weekend warriors and frequent hikers reliable long-term support. For anyone looking for a reliable, no-nonsense hydration companion for short trail loops, scouting hikes, or hot festival afternoons, this compact pack delivers high utility and dependable comfort.

Weighing approximately 13.4 ounces empty, the Hydrobak adds negligible weight to your gear loadout. Its slender silhouette sits close to the spine, minimizing bounce and pack shifting while walking across uneven trails or cycling down winding gravel paths.

Because of its compact frame, campers can easily slide the Hydrobak flat inside a larger 50-liter backpacking pack, suitcase, or vehicle organizer box. This makes it an exceptional summit bag or quick day-trip companion once you establish basecamp.

To preserve fresh-tasting water and extend the life of the Crux reservoir, rinse the bladder with warm water and mild soap after each outing. Hanging the bladder upside down with the cap open allows air to circulate thoroughly, preventing moisture accumulation.

The nylon exterior can be spot cleaned with a damp cloth and mild detergent if it encounters trail dust or mud. Avoid machine washing or harsh chemicals to protect the fabric weave, zippers, and mesh shoulder straps.

The Fly Racing Hydro Pack is a streamlined hydration backpack designed for quick outdoor excursions, day hikes, and active trail outings. Built with a minimalist footprint, it caters to day hikers, trail runners, mountain bikers, solo adventurers, and festival goers who need dependable fluid replacement without the bulk of a full-sized daypack. Campers heading out from base camp for a quick ridge scramble will appreciate its straightforward, low-profile build that keeps bulk to a bare minimum.

Equipped with a 70 oz (approximately 2.1-liter) water bladder, this pack supplies enough liquid for several hours on sun-drenched footpaths or dusty singletrack. The integrated high-flow bite valve allows you to take in fluids easily without fumbling with screw-top bottles or stopping on the trail. For outdoor enthusiasts setting up a weekend campsite and taking off on afternoon trail excursions, this setup delivers dependable hands-free hydration while navigating rocky paths, desert washes, or humid woodland trails.

Constructed with rugged nylon fabric, the pack holds up against brush scrapes, branch snags, and routine campsite dirt. Fully adjustable mesh shoulder straps promote airflow across the chest and shoulders, helping to reduce sweat accumulation on warm summer treks. In addition to housing the fluid reservoir, the pack includes two external stash pockets that provide convenient storage for energy chews, a pocket knife, car keys, a compact headlamp, or basic first aid items.

At well under one pound unloaded, carrying this pack creates minimal fatigue on the trail. However, potential buyers should recognize its capacity boundaries. With only two compact exterior pockets, you will not have room for bulky rain gear, camp cooking stoves, or extra fleece layers for chilly evenings. The minimalist harness also lacks a load-bearing hip belt, making it strictly suited for fast-and-light adventures rather than heavy hauling.

For car campers, day hikers, festival attendees, and budget-conscious outdoor enthusiasts looking for an accessible, lightweight hydration carrier, the Fly Racing Hydro Pack delivers reliable utility. It serves as an excellent companion pack to keep stashed in your vehicle trunk or camp gear bin, ready to deploy whenever a spontaneous hike or trail ride calls for quick, hassle-free hydration.

Weighing around 0.9 pounds empty, this pack keeps your trail profile slim and agile. The 70 oz reservoir sits flat against your back, helping prevent uncomfortable sloshing and balance disruption while trekking steep switchbacks or biking around campground loops.

The breathable mesh shoulder straps adjust smoothly across different torso sizes, ensuring the pack stays stable without trapping excessive body heat during high-exertion hikes in warm summer weather.

To maintain fresh-tasting water, rinse the hydration bladder with warm water and mild dish soap after every trail outing. Allow the reservoir, hose, and bite valve to air dry completely before storing to prevent moisture buildup.

The exterior nylon fabric can be spot cleaned using a damp cloth and mild detergent. Avoid machine washing or harsh chemical solvents to preserve the integrity of the pack fabric and seams across multiple camping seasons.

The N NEVO RHINO 12L Hydration Backpack is an ultralight daypack engineered to deliver convenient, hands-free hydration during fast-paced outdoor activities. Built for day hikers, trail runners, mountain bikers, and music festival goers, this minimalist pack blends a 2-liter fluid reservoir with functional cargo capacity. For budget-conscious adventurers and weekend warriors tackling steep inclines or all-day outdoor events, it provides a lightweight alternative to bulkier daypacks without sacrificing essential storage for trail snacks, sun protection, and emergency layers.

On the trail, the pack shines during sustained aerobic activity thanks to its ergonomic weight distribution and steady fluid delivery. The included 2-liter BPA-free PEVA bladder slides neatly into a dedicated rear compartment, utilizing a reliable slide-top opening that makes scooping mountain spring water or filling at campground spigots painless. A fast-flow bite valve with a secure push-pull shutoff prevents annoying drips on steep descents or bumpy switchbacks. While the bladder supplies ample water for short to moderate treks, outdoor enthusiasts will appreciate the dual sternum straps that cinch down tight, preventing annoying bounce when jogging down rocky paths or dancing through festival grounds.

Constructed from tear-resistant nylon treated with a light PU coating, the pack exterior handles rough encounters with tree branches, granite rock faces, and sudden passing drizzle. Honeycomb air-mesh padding across the back panel and shoulder harness encourages continuous ventilation, helping to manage sweat and prevent uncomfortable hotspots when hiking under direct sun. The pack also incorporates dual stretch mesh pockets on the front straps, large enough to fit a modern smartphone, sunscreen, or nutrition gels. A low-profile bungee system and exterior clips offer handy attachment points for a cycling helmet, light windbreaker, or trekking accessories.

While the pack offers impressive functionality, prospective buyers should consider a few practical quirks. As is common with many budget-friendly PEVA reservoirs, user feedback notes a mild plastic taste right out of the box, requiring a thorough flush with warm water, baking soda, or lemon juice before the first trek. Drying the narrow drinking tube and reservoir corners after a trip also takes a bit of care to prevent moisture buildup. Additionally, runners moving at high speeds may notice the drinking hose occasionally slipping from its shoulder clip without an extra keeper ring.

For solo hikers, car campers seeking a reliable day trek companion, and festival campers preparing for hot summer weekends, this 12-liter hydration pack provides outstanding utility and comfortable load-bearing performance. It easily accommodates trail snacks, a compact rain shell, and essential gear while keeping vital fluids easily accessible. If you need an agile, featherlight hydration daypack that balances solid durability with budget-friendly practicality, the N NEVO RHINO pack makes a dependable addition to your outdoor gear lineup.

To ensure clean-tasting water on every backcountry trek, rinse the 2-liter bladder thoroughly before its first outing with warm water and a teaspoon of baking soda or lemon juice. Allow the solution to sit for several hours, flush it through the drinking hose, and rinse clean.

After returning from your outdoor hike or festival, drain all remaining water immediately. Hang the bladder upside down using a dedicated reservoir hanger or insert a clean paper towel or kitchen whisk inside the bladder to keep the interior walls separated for proper airflow. Clean the exterior nylon pack with a damp cloth and mild soap, then air dry completely away from direct high heat.

This hydration pack works exceptionally well for both rugged mountain trails and crowded music festivals. The dual zippered chest pockets allow you to keep your smartphone, identification, credit cards, and ear protection right against your chest, offering quick access and enhanced security in crowded venues.

The low-profile 12-liter footprint complies with most festival bag guidelines while still offering sufficient space for electrolyte packets, a light jacket, sunglasses, and an emergency rain poncho. Adjust the two chest clips to secure the pack tightly against your torso to prevent shifting when moving through crowded trailheads or dance fields.
