How to Choose the Right Dry Storage for River Trips

River rafting exposes your gear to prolonged water submersion, high-pressure splashes, and abrasive rocks. To protect your equipment, you must prioritize the bag’s materials and construction methods over flashy features. Look for heavy-duty TPU (thermoplastic polyurethane) or thick, PVC-coated nylon with welded seams rather than sewn and taped seams, which fail under heavy water pressure.

Different gear categories require different styles of closure to remain dry and functional. Roll-top closures are excellent for compressible camp gear, while airtight zippers and molded gaskets offer true submersible protection for sensitive items. Hard-sided cases provide unmatched crushproof defense but lack the flexibility to pack into tight boat corners.

Always match your gear capacity to the actual rigging space available on your raft. Oversized bags are difficult to tie down securely, while too many small bags create a chaotic deck layout that is tough to manage. A balanced setup utilizes a primary outfitter bag for camp gear, a mid-sized waterproof backpack for day-use items, and small utility boxes for essentials.

Submersible Duffel – YETI Panga 50 Dry Duffel

A submersible duffel bridges the gap between easy-access luggage and elite waterproof protection. When gear sits in a puddle on the raft floor or gets dunked during a flip, this style of bag keeps water completely out. It serves as your primary gear locker for dry clothes, camp footwear, and clean layers that must stay protected at all costs.

The YETI Panga 50 Dry Duffel stands out because of its Hydrolok zipper, which creates a completely airtight, submersible barrier. Built with high-density nylon and a thick TPU lamination, the outer shell resists punctures and abrasions from rough raft frames and gravel riverbanks. Its molded bottom provides structure, making packing and unpacking incredibly straightforward compared to traditional, floppy dry bags.

• Capacity: 50 Liters (also available in 75L and 100L)
• Best Used For: Multi-day clothing, camp gear, and personal valuables
• Key Feature: Submersible Hydrolok Zipper and ThickSkin Shell

The zipper requires a firm pull and regular lubrication with the included wax to function smoothly. This premium duffel is perfect for paddlers who need absolute security for mid-sized gear, but it is a substantial financial investment if you only run calm flatwater.

Waterproof Hard Case – Pelican 1400 Protector Case

Sensitive electronics, cameras, and first-aid kits require more than just water protection; they need crushproof armor. Rafts bounce off canyon walls, gear shifts violently during wraps, and heavy cooler frames can easily crush soft bags. A hard-sided case provides a rigid sanctuary for your most fragile, high-value gear.

The Pelican 1400 Protector Case is the industry standard for compact, indestructible protection. It features an automatic pressure equalization valve that balances interior pressure when changing altitudes—a crucial feature for river trips descending through deep canyons. The open-cell core with solid wall construction ensures it can survive being wedged under heavy gear or stepped on by heavy boots.

• Internal Dimensions: 11.80″ x 8.80″ x 5.20″
• Best Used For: DSLR cameras, hand-held radios, and medical kits
• Key Feature: Automatic Pressure Equalization Valve and Pick ‘N’ Pluck foam

The Pick ‘N’ Pluck foam interior allows for custom-tailored gear protection, but once plucked, it is hard to reconfigure for different gear shapes. It takes up a fixed volume on your boat, meaning it does not compress as you use up its contents. This case is indispensable for photographers, though it is impractical for soft items like clothing or sleeping bags.

Outfitter Dry Bag – NRS Bills Bag 110L Dry Backpack

Multi-day expeditions demand massive storage capacity for sleeping bags, tents, and bulky camp layers. An outfitter-grade dry bag acts as the workhorse of your raft, swallowing large volumes of gear and keeping it dry under the heaviest waves. It must be rugged enough to sit at the bottom of the gear pile and easy to carry up steep, muddy riverbanks to camp.

The NRS Bills Bag 110L Dry Backpack is a legendary piece of river gear, constructed from heavy-duty 21-ounce Tredlox PVC-free polyester. Its massive 110-liter capacity is secured by a classic fold-down StormStrip closure that provides a reliable seal when rolled correctly. Adjustable, padded backpack straps make hauling heavy gear over rocky terrain remarkably painless, and they can be removed when rigging the bag to the raft.

• Capacity: 110 Liters
• Best Used For: Sleeping bags, tents, and bulky camp gear
• Key Feature: Removable backpack harness and Tredlox material

This bag is massive, meaning it can become incredibly heavy and awkward if packed to maximum capacity with dense gear. It utilizes a roll-top closure, which is highly water-resistant but not rated for prolonged, deep submersion like a zippered duffel. This is the ultimate gear hauler for multi-day river runners, but it is far too large and bulky for simple day trips.

Waterproof Backpack – Watershed Animas Submersible

During day hikes up side canyons or scouting runs from the shore, you need a dry bag that transitions easily from the raft deck to your back. A waterproof backpack protects day-use essentials like cameras, rain shells, and lunch. It keeps these items dry and accessible while keeping your hands free to navigate rugged terrain.

The Watershed Animas Submersible stands apart due to its proprietary ZipDry closure system, which works like a heavy-duty, airtight freezer bag seal. This closure is completely submersible, meaning your gear remains dry even if the backpack floats down a rapid solo. Constructed with polyurethane-coated nylon, it is highly abrasion-resistant and remains supple even in freezing mountain water.

• Capacity: 40 Liters
• Best Used For: Side-canyon hiking, day-use layers, and lunch
• Key Feature: Airtight ZipDry closure and rugged lash points

The ZipDry closure has a slight learning curve and requires regular application of 303 Protectant to open and close smoothly. It lacks external mesh pockets or water bottle holders to maintain its waterproof integrity, which some hikers may find inconvenient. This backpack is perfect for active river runners who love side-canyon exploration, but it may feel overly technical for those who stay in the boat.

Lightweight Dry Sack – Sea to Summit Big River Bag

Not every piece of gear on a raft needs heavy-duty, outer-armor protection. Lightweight dry sacks are designed to organize and protect gear inside larger, non-waterproof compartments, or to act as secondary protection inside zippered duffels. They prevent damp gear from contaminating dry items and keep small essentials organized.

The Sea to Summit Big River Bag is built from tough 420D ripstop nylon, offering excellent abrasion resistance without the heavy bulk of traditional PVC bags. It features low-profile Hypalon lash loops on the sides, allowing you to secure it directly to a kayak deck or raft frame if needed. The interior has a white polyurethane coating that increases visibility, making it much easier to find small items at the bottom of the bag.

• Sizes Available: 5L to 65L
• Best Used For: Organizing sleeping clothes, camp pillows, or food inside larger bags
• Key Feature: Space-saving design and durable Hypalon lash loops

While highly durable for its weight, this dry sack should not be used as a primary external bag on a raft frame where it will rub directly against metal or sharp rock edges. It relies on a roll-top closure, which requires at least three tight rolls to prevent water intrusion. This bag is excellent for organized rafters looking for reliable internal compartmentalization.

Raft Deck Bag – Watershed Colorado Dry Duffel

A raft deck bag sits right in the splash zone, often rigged on top of the gear pile or directly behind the rower’s seat for quick access. This bag must handle constant, high-pressure waves while offering a wide opening so you can grab gear quickly during short stops on the river.

The Watershed Colorado Dry Duffel is the gold standard for expedition raft rigging. Its wide, top-loading ZipDry closure allows you to store and access bulky items like sleeping bags and camp chairs without struggling through a narrow opening. Built with Kevlar-reinforced wear patches and heavy-duty webbing tie-down points, it is designed to withstand the immense pressure of cam straps holding it to a raft frame.

• Capacity: 75 Liters
• Best Used For: Rigging on the raft deck for quick access to warm layers and safety gear
• Key Feature: Wide-mouth ZipDry closure and Kevlar-reinforced wear patches

At 75 liters, it occupies a significant footprint on your raft and requires proper rigging to prevent it from catching wind. Because of its airtight seal, you must compress the air out before sealing it, or it will act like a giant balloon on your deck. This is a must-have for serious expedition rafters who need quick access to bulk gear, but it is too large for small paddle rafts or inflatable kayaks.

Waterproof Phone Case – Pelican Marine Floating Case

Your phone serves as your camera, GPS, and emergency communication device on the river, making its protection paramount. A dedicated waterproof phone case keeps your device functional and dry. It allows you to take photos on the fly without risking drop or water damage.

The Pelican Marine Floating Case features built-in air cushions that ensure your phone floats to the surface if dropped in deep water. The clear, touch-sensitive window allows for seamless screen operation, so you can snap quick photos or check maps without removing the phone from safety. It also includes a heavy-duty lanyard to secure the phone directly to your personal flotation device (PFD).

• Compatibility: Fits most smartphones up to 6.7 inches
• Best Used For: Quick-access photography and navigation on the water
• Key Feature: Floating design and touch-sensitive screen window

The thick material can slightly muffle phone audio during calls, and touchscreens can become unresponsive when wet screen-to-surface contact occurs under rushing water. It is designed to fit most standard smartphones, but oversized cases may need to be removed first. This is a vital safety tool for any river runner, though it is not intended for deep underwater photography.

Utility Dry Box – Plano Guide Series Waterproof Case

Small, loose items like fishing licenses, lighters, repair patches, and multi-tools easily get lost or ruined if left loose in a bag. A compact utility dry box keeps these daily essentials organized, dry, and instantly accessible in a hard-sided, protective container.

The Plano Guide Series Waterproof Case features a cam-action latch system and a Dri-Loc O-ring seal that creates a completely dustproof and waterproof barrier. It is constructed from a thick, polycarbonate shell that resists impacts and prevents cracking when stepped on or dropped onto rocks. Inside, a soft TPR lining cushions delicate items like sunglasses or keys from rattling around during rough rapids.

• Dimensions: Available in multiple sizes (3600 and 3700 series)
• Best Used For: Wallets, keys, permits, lighters, and multi-tools
• Key Feature: Dri-Loc O-ring seal and clear polycarbonate construction

This utility box does not float when loaded with heavy metal tools, so securing it with a lanyard or carabiner is essential. The latches are tight and secure, which can make them difficult to open with cold, wet hands. It is an exceptional choice for anglers, rowers, and gear heads who need a dedicated, indestructible space for pocket-sized gear.

How to Secure and Rig Dry Gear on a River Raft

Proper rigging is the difference between a minor splash and a catastrophic gear loss during a flip. Always secure your heaviest dry bags low and central in the raft’s cargo bays to maintain a low center of gravity. Use high-quality 1-inch polypropylene cam straps rather than stretchy bungee cords, which can fail under the hydraulic pressure of a rapid.

Run your cam straps through the dedicated lash loops or carry handles of your dry bags, ensuring the straps loop around the metal frame of the raft. Avoid rigging bags so tightly that you compress the zippers or air seals, as this can cause them to fail under pressure. Double-thread your buckles and tuck away any loose strap tails to prevent them from becoming entanglement hazards in a swim.

Finally, practice the “flip test” mentality: assume your raft will turn upside down in the next rapid. Shake your rigged bags to ensure there is zero shifting or loose play. If a bag can slide out or dangle more than a few inches when the boat is inverted, adjust your strap configuration before pushing off from the eddy.

How to Clean and Maintain Waterproof Zippers

Waterproof zippers are engineering marvels, but they are highly susceptible to damage from fine river sand, silt, and salt crust. If grit gets trapped in the zipper teeth, it can tear the protective polyurethane coating or force the zipper slider off track, ruining the bag’s waterproof integrity. Cleaning your zippers after every river trip is mandatory to extend the lifespan of your expensive gear.

Start by rinsing the zipper thoroughly with fresh, clean water to flush out loose sand and debris. Use a soft-bristled toothbrush to gently scrub between the zipper teeth and along the sealing lips where dirt loves to hide. Once clean, dry the zipper completely with a clean towel; storing a wet bag with a closed zipper can lead to mold and material degradation.

After cleaning, apply a thin layer of manufacturer-approved lubricant, such as zipper wax or silicone grease, directly to the zipper teeth. Slide the zipper back and forth a few times to distribute the lubricant evenly, ensuring smooth operation for your next launch. Never force a sticky zipper, as this can permanently strip the teeth and ruin the airtight seal.

Testing Your Dry Gear Seals Before Launching

Never assume a dry bag is waterproof just because of its brand name or price tag; pinholes, dry rot, and misaligned seals can develop during off-season storage. Testing your gear at home before you reach the boat ramp prevents ruined gear and high-stress situations on the water. A simple, proactive inspection takes only a few minutes but saves days of headache.

For soft dry bags, perform an inflation test. Close and seal the bag with a small amount of air trapped inside, then gently squeeze the bag to compress the air. Listen closely for hissing sounds or feel for escaping air along the seams, roll-tops, and zipper lines. If you suspect a leak, submerge the inflated bag in a bathtub or pool and look for bubbles rising to the surface to pinpoint the exact leak location.

For hard cases and utility boxes, place a dry sheet of paper towel inside, seal the latches, and submerge the case in a tub of water for a few minutes. Remove the case, dry the exterior completely, and open it to inspect the paper towel. If the paper towel is bone-dry, your O-ring seal is fully intact and ready to handle the rapids.

Equipping your raft with a strategic mix of rugged dry duffels, crushproof hard cases, and reliable utility boxes keeps your gear safe regardless of what the river throws your way. By investing in high-quality seals and maintaining them properly, you can focus on navigating the rapids instead of worrying about your gear. Pack smart, rig tight, and enjoy the peace of mind that comes with bone-dry gear on every launch.
