9 Best Dry Bags for River Rafting Trips

Watching a wall of whitewater curl over the bow of a raft is thrilling until you realize your dry clothes are soaking in the bilge. Choosing the right dry bag is not just about keeping gear dry; it is about organizing your life on the river so you can focus on navigating the rapids. Having the correct mix of specialized waterproof storage ensures that sleeping bags stay bone-dry and cameras remain functional throughout multi-day expeditions.

How to Match Dry Bag Capacity to Your River Trip

Selecting the wrong size dry bag leads to two common river disasters: a bag so stuffed the roll-top cannot seal, or a massive, half-empty sack taking up valuable frame space. Capacity is measured in liters, and matching this volume to the duration of the trip is the first step in rigging a clean boat. Day trips require very different configurations than self-support multi-day runs.

For quick day runs, a 10-liter to 20-liter bag is ideal for extra layers, lunch, and small personal items. Overnighters or weekend trips generally demand a 30-liter to 65-liter main bag per person to house a compact sleeping bag, tent body, and dry clothing. True wilderness expeditions lasting four days or more require the heavy artillery—110-liter behemoths or large submersible duffels that can swallow bulky sleep systems and cold-weather gear.

Keep weight distribution in mind when packing these larger volumes. Heavy items like canned food or spare hardware should never go in a massive shoulder-strapped dry bag meant for camp gear. Instead, reserve high-capacity bags for lightweight, compressible items, and use smaller, dedicated bags for dense, heavy equipment to keep the raft’s center of gravity low.

Expedition Duffel – NRS Bill’s Bag 110L

A high-capacity expedition bag is the backbone of any multi-day river packing system. It functions as the primary gear vault, holding sleeping bags, camp clothes, and bulky gear that must stay dry until camp is pitched. This category requires extreme durability because these bags sit at the bottom of the gear pile, subjected to constant moisture and friction against the raft frame.

The NRS Bill’s Bag 110L remains the industry standard for expedition hauling due to its rugged 21-ounce TUSA-coated PVC construction. The heavy-duty bottom basin resists punctures when dragged over gravel bars, while the classic roll-top closure keeps water out even during swim situations. The adjustable, padded shoulder straps turn a miserable portage into a manageable hike, and they can be completely removed when rigging the bag into the raft.

• Capacity: 110 Liters
• Material: 21 oz TUSA-coated PVC polyester
• Closure: StormStrip roll-top system
• Best for: Multi-day expeditions, group gear hauling, and portages

Keep in mind that a fully loaded 110-liter bag can easily exceed 50 pounds, making it a beast to lift into a high-sided raft. It is also entirely non-subdivided, meaning small items will get lost at the bottom without internal packing cubes. This bag is perfect for river runners who need to move massive amounts of gear from boat to beach, but it is far too bulky for casual day trips or solo kayakers.

Backpack Dry Bag – Sea to Summit Hydraulic Pack

When the river channel is blocked by a rockslide or a massive logjam, portaging becomes inevitable. Carrying standard dry bags by their grab handles over slippery boulders is a recipe for a twisted ankle. A dedicated backpack dry bag bridges the gap between waterproof storage and a true expedition backpack, transferring the weight to the hips for safe, hands-free travel.

The Sea to Summit Hydraulic Pack stands out because of its engineered heavy-duty harness system, which features open-mesh foam and breathable fabrics to handle heavy loads comfortably. Built from 600D TPU laminated fabric, this bag resists UV rays and cold temperatures without cracking or stiffening. The harness can also be completely detached when securing the bag to a raft frame, preventing loose straps from becoming dangerous snag hazards in swift water.

• Capacity options: 35L, 65L, 90L, 120L
• Material: 600D TPU laminated nylon
• Harness: Removable, adjustable EVA-foam suspension
• Best for: Portages, canyon hikes, and wet gear hauling

While the harness is exceptionally comfortable, the hardware adds weight and complexity compared to a standard dry sack. This pack is a premium investment that is unnecessary if the raft always pulls right up to flat, sandy camp spots. However, for wilderness rivers with mandatory portages or steep canyon climbs, this pack prevents physical exhaustion and protects gear from catastrophic drops.

Submersible Duffel – Watershed Colorado Dry Bag

Traditional roll-top bags are highly water-resistant, but they can still weep water under prolonged submersion or intense water pressure. For critical gear like high-end camera bodies, warm down jackets, or medical kits, a fully submersible duffel is non-negotiable. These bags rely on mechanical, airtight seals rather than folded fabric to keep water out under any condition.

The Watershed Colorado Dry Bag utilizes an innovative ZipDry closure system, which seals shut like a heavy-duty freezer bag to create an airtight, submersible barrier. Constructed from polyurethane-coated ballistic nylon, it is significantly more abrasion-resistant and pliable in cold weather than standard PVC bags. The duffel-style opening runs the length of the bag, offering immediate visibility and access to gear without digging through a deep column.

• Capacity: 75 Liters
• Closure Type: ZipDry airtight seal
• Material: 420D double-density polyurethane-coated nylon
• Best for: Class IV-V whitewater, sensitive electronics, and winter rafting

The ZipDry seal is incredibly secure, but it requires periodic maintenance with a UV-protectant lubricant to prevent it from becoming stiff and difficult to close. Users must also master the technique of pinching and pulling the seal to open it, which can be challenging with cold hands. This bag is an overkill choice for flat-water floaters, but it is the ultimate insurance policy for running violent, continuous whitewater.

Compression Sack – Sea to Summit eVent Dry Sack

Space is at a premium on any raft, especially when packing bulky synthetic sleeping bags and winter fleece layers. Standard dry bags trap air inside, leaving them puffy and difficult to pack efficiently next to other gear. An air-permeable compression dry sack solves this by allowing air to be squeezed out of the bottom while keeping water from getting back in.

The Sea to Summit eVent Dry Sack excels by utilizing waterproof, air-permeable eVent fabric on the base. This design allows users to roll the top down and compress the contents, pushing excess air out through the fabric base without needing a mechanical valve. Made from 70D nylon fabric with fully taped seams, it provides excellent durability while keeping the overall bag weight remarkably low.

• Capacity options: 6L to 30L
• Base Material: Air-permeable eVent laminate
• Body Material: 70D nylon with DWR finish
• Best for: Sleeping bags, down jackets, and internal space-saving

It is crucial to understand that this sack is designed as an internal dry system; the 70D nylon is too thin to withstand direct contact with sharp raft frames or abrasive sandy beaches. Always pack this compression sack inside a heavy-duty exterior duffel or hatch compartment. It is the perfect tool for backpacking rafters who need to minimize gear volume without sacrificing waterproof reliability.

Heavy-Duty Duffel – Yeti Panga 50 Submersible

A heavy-duty submersible duffel is designed to survive the harshest environments on earth, from desert canyons with abrasive sandstone to freezing glacial rivers. These bags serve as a personal locker, protecting gear from rain, waves, and the rough handling of loading and unloading. They do not rely on roll-tops, using heavy-duty zippers to seal out water instead.

The Yeti Panga 50 Submersible is built like an absolute tank with a ThickSkin shell made of high-density nylon and TPU lamination. The Hydrolok zipper provides a completely airtight, waterproof seal that guarantees dry contents even when dragged through rapids or strapped to the floor of the raft. An EVA molded bottom provides a rugged structure that prevents the bag from collapsing, making it incredibly easy to pack and unpack.

• Capacity: 50 Liters
• Zipper: Hydrolok waterproof zipper
• Material: High-density nylon shell with TPU coating
• Best for: Rough handling, camera gear, and weekend river trips

The Panga is exceptionally stiff and heavy compared to traditional dry bags, which makes it less pliable when trying to squeeze it into tight spaces under a raft seat. The premium price tag is also a significant consideration for casual weekend rafters. However, for those who demand absolute structural integrity and a zipper that will not blow out under pressure, this duffel is unmatched.

Clear Dry Bag – SealLine Baja View Dry Bag

Digging through an opaque dry bag to find a first aid kit or a matching dry sock while shivering on a riverbank is frustrating and time-consuming. Clear dry bags solve this organizational nightmare by allowing the user to scan the contents without breaking the watertight seal. They are invaluable for storing emergency gear that must be located in seconds.

The SealLine Baja View Dry Bag features a highly transparent, PVC-free polyurethane body that allows for instant gear identification. Unlike cheap clear vinyl bags that stiffen and crack in the cold, this bag uses a premium, flexible polyurethane that maintains its integrity across temperatures. The heavy-duty 1000D polyurethane-coated polyester bottom ensures it can sit on abrasive river rocks without wearing through.

• Capacity options: 5L, 10L, 20L
• Material: PVC-free polyurethane body, 1000D bottom
• Closure: DrySeal roll-top
• Best for: First aid kits, boat repair supplies, and daily layers

Be aware that clear materials can create a greenhouse effect, heating up internal contents when left in direct sunlight on a hot raft. Avoid storing heat-sensitive items like medications or electronics directly against the transparent walls without a buffer layer. This bag is an essential addition to any raft setup for safety-critical gear, though it is not meant to replace a large camp duffel.

Personal Dry Bag – Earth Pak Waterproof Bag

While heavy-duty gear haulers manage the camp setup, every rafter needs a small personal dry bag close at hand during the day. This bag rides in the passenger compartment, holding sunscreen, snacks, a warm fleece, and a dry towel. It needs to be easy to open, simple to secure, and tough enough to handle splashes and muddy floorboards.

The Earth Pak Waterproof Bag offers phenomenal value and reliability, constructed from durable 500D PVC material. It features a classic roll-top closure that seals out heavy splashes and brief dunks, keeping personal items completely dry. The included adjustable shoulder strap makes it easy to carry up to lunch spots on the riverbank, and the built-in D-rings provide convenient tie-down points for the raft.

• Capacity options: 10L, 20L, 30L, 40L, 55L
• Material: 500D waterproof PVC
• Accessories: Single shoulder strap (10L/20L), backpack straps (30L/40L/55L)
• Best for: Day floats, personal item storage, and budget-conscious paddlers

Note that this bag is not rated for prolonged submersion under heavy water pressure, so it should not be rigged where it will sit submerged in a deep bilge pocket. The basic shoulder strap is functional for short walks but lacks the support needed for long-distance portaging. It is the perfect, no-nonsense choice for keeping day-use essentials dry and accessible.

Phone Dry Pouch – JOTO Waterproof Case

A phone on a river rafting trip is both a camera and a lifeline, but it is highly vulnerable to dropping into the bilge or falling overboard. Keeping it buried in a large dry bag means missing those once-in-a-lifetime photos of wildlife or rapids. A dedicated, wearable phone dry pouch keeps the device safe from splashes while allowing full touchscreen access.

The JOTO Waterproof Case features an IPX8 waterproof rating, certifying it for submersions up to 100 feet. The dual-sided clear windows allow for clean photos and video without removing the phone from the protective barrier. A simple, secure snap-and-lock seal at the top ensures that silt, mud, and water cannot breach the opening, even if the user goes for a swim.

• Waterproof Rating: IPX8 (up to 100 feet)
• Compatibility: Fits smartphones up to 7 inches diagonally
• Included: Adjustable neck lanyard
• Best for: Quick photography, emergency navigation, and splashing environments

Keep in mind that water on the outside of the screen can confuse capacitive touchscreens, making it difficult to snap photos while wet; using the phone’s physical volume buttons to trigger the camera is a useful workaround. Additionally, this case does not provide flotation, so adding a buoyant wrist strap or securing the lanyard to a life jacket is essential to prevent the phone from sinking to the river bottom.

Roll-Top Duffel – OverBoard Waterproof Duffel

Vertical dry bags are excellent for packing deep, but finding a specific item often requires emptying the entire bag onto a muddy bank. A roll-top duffel solves this by offering a wide, horizontal opening that provides immediate access to all gear at once. This design combines the convenience of a traditional travel duffel with the waterproof security of a dry bag.

The OverBoard Waterproof Duffel utilizes a reliable Fold Seal System along the main horizontal opening, providing a secure, IP66-rated barrier against dust, mud, and heavy water spray. Constructed from heavy-duty 600D PVC tarpaulin, it easily withstands the friction of being cinched under tight straps on a raft frame. Inside, a handy zip pocket helps separate clean clothes from damp river gear.

• Capacity options: 40L, 60L, 90L, 130L
• Material: 600D PVC tarpaulin
• Waterproof Rating: IP66 (floats if dropped in water)
• Best for: Organized packing, weekend trips, and easy gear access

Because the roll-top closure runs horizontally, it requires careful folding—at least three tight wraps—to prevent water from seeping in through the ends during a long swim. It is slightly more prone to user-error leaks than a standard vertical dry bag if packed too full to roll properly. This duffel is highly recommended for rafters who prioritize organized, quick-access storage over deep-water submersion capability.

How to Properly Secure Dry Bags to a Raft Frame

Rigging dry bags to a raft frame is an art form that balances boat stability with gear security. A loose bag can act as a sail in heavy winds, throw off the balance of the raft in a rapid, or get swept away during a flip. The golden rule of river rigging is: “Flip-proof and strip-proof.” Everything on the boat must stay secured even if the raft is completely upside down in a violent current.

Always use 1-inch polypropylene cam straps to secure dry bags, and completely avoid elastic bungee cords, which stretch and break under pressure. Run the cam straps through the bag’s built-in D-rings or carry handles, then wrap them around the structural frame of the raft. Avoid relying solely on the plastic buckles of a roll-top bag to hold it to the frame, as these buckles are not designed to bear the weight of a shifting boat.

When packing the cargo floors, place the heaviest submersible duffels at the bottom of the stack to keep the center of gravity low. Layer the lighter roll-top bags and personal gear on top, then secure the entire pile with a heavy-duty cargo net or a web of cam straps. Before launching, grab each dry bag and give it a firm shake; if the bag shifts or moves independently of the frame, tighten the straps until the bag is locked in place.

Essential Cleaning and Storage Tips for Longevity

Dry bags are a major investment, but simple maintenance will keep them functional for years of river trips. Sand and silt are the silent killers of dry bag seals, acting as sandpaper that wears down waterproof coatings and ruins zippers. After every trip, take the time to thoroughly hose down both the interior and exterior of each bag with fresh water to remove all river debris.

Mold and mildew can ruin a dry bag’s interior fabric and create foul odors that ruin clean clothes. Never store a dry bag rolled up or zipped closed while it is still damp; instead, hang them upside down in a shaded, well-ventilated area until they are completely dry inside and out. For roll-top bags, leave the collars unrolled during storage to prevent the material from taking a permanent crease that could weaken the waterproof seal.

For high-end submersible bags with waterproof zippers or rubber seals, apply a thin layer of zipper lubricant to keep the mechanisms moving smoothly. Store the bags in a temperature-controlled space away from direct sunlight and extreme heat, which can degrade the glues and plastics over time. Taking these quick steps ensures that when the next river trip rolls around, the gear is clean, functional, and ready to face the rapids.

Conclusion

Navigating wild rivers requires gear that rises to the challenge and keeps critical equipment safe from the elements. Equipping a raft with the right combination of submersibles, compression sacks, and rugged duffels transforms a stressful trip into a seamless outdoor adventure. With gear securely packed and properly rigged, the only thing left to do is push off from the bank and enjoy the current.
