8 Waterproof Storage Picks to Keep Gear Dry on a Stand Up Paddleboard

Picture paddling out onto a glass-calm lake at sunrise, only to have a sudden boat wake capsize your board and send your phone, dry clothes, and car keys sinking to the bottom. Stand up paddleboarding exposes your gear to constant splashes, paddle drips, and the ever-present risk of complete submersion. Equipping your board with reliable, specialized waterproof storage is the single best way to protect your valuables and ensure a stress-free day on the water.

Understanding SUP Waterproof Ratings and Gear Needs

Not all “waterproof” gear is created equal, especially when strapped to the deck of a paddleboard. Gear ratings typically range from splash-resistant to fully submersible, and choosing the wrong one can result in ruined electronics. Knowing the difference between an IPX6 rating (withstands heavy sprays) and an IPX8 rating (survives prolonged submersion) is critical before heading out.

On a SUP, your gear sits inches from the water line and is subject to constant splashing, paddle drip, and occasional flips. A simple splash-proof pouch might handle a light drizzle, but it will fail instantly if your board flips and the bag gets pinned underwater. Matching the rating to the vulnerability of the item—like reserving hard cases for keys and roll-tops for extra layers—keeps your gear intact.

Environmental factors like saltwater corrosion and intense UV exposure also degrade materials faster than you think. Look for bags made from thermoplastic polyurethane (TPU) or heavy-duty nylon with welded seams rather than stitched ones. These materials resist punctures from beach gravel and won’t crack after hours under the blazing sun.

SUP Deck Bag – Sea to Summit Solution Gear

A dedicated deck bag is the cockpit of your paddleboard, keeping essentials like sunscreen, water, and snacks within arm’s reach while you paddle. Unlike loose dry sacks, a true deck bag sits flat, resists wind drag, and anchors directly to your board’s rigging. It prevents gear from rolling around or sliding off the nose when you hit choppy water or boat wakes.

The Sea to Summit Solution Gear Deck Bag excels here because of its low-profile, contoured design and robust build. It features heavy-duty lash points and quick-release buckles that integrate seamlessly with standard SUP deck plugs. The easy-to-use roll-top closure paired with a stiffening strip ensures a reliable, watertight seal without fuss.

• Capacity: 12 Liters
• Material: 420D waterproof fabric
• Best Uses: Storing sunscreen, water bottles, snacks, and windbreakers
• Attachment Method: Heavy-duty straps with quick-release buckles

While it excels at shedding heavy spray and temporary wash-overs, it is not designed for underwater salvage missions. Keep your highly sensitive, non-waterproof electronics inside a secondary dry pouch inside this bag for double protection. Also, ensure you rinse the salt out of the aluminum buckles after ocean paddles to prevent binding.

This deck bag is perfect for recreational paddlers who want organized, quick-access storage during day trips. It is not the right fit for multi-day touring enthusiasts who need massive, expedition-sized dry storage or those with boards lacking deck rigging points.

Dry Backpack – Earth Pak Waterproof Backpack

When your paddleboarding adventure involves hiking to remote launch sites or portaging between lakes, a handheld dry bag quickly becomes a hassle. A dry backpack transfers the weight to your shoulders, leaving your hands free to carry your paddle and board. It serves as your main cargo hold on the water and your portage pack on land.

The Earth Pak Waterproof Backpack is built from commercial-grade materials with thermo-welded seams, making it virtually indestructible. It features comfortable padded shoulder straps, a chest strap for stability, and a heavy-duty roll-top closure system that seals out all moisture. The exterior zippered pocket offers quick access to small items, though that specific pocket is only water-resistant.

• Capacity Options: 35L and 55L
• Material: Heavy-duty 500D PVC
• Best Uses: Portages, day hikes, camping gear, and dry clothing layers
• Key Feature: Ergonomic back panel with MOLLE system loops

Users should note that PVC can become stiff in colder water temperatures, making the roll-top closure slightly harder to roll tightly. Air can also get trapped inside during sealing, causing the bag to balloon; simply purge the air before rolling to keep it compact. Match the capacity carefully to your physical stature so the pack does not throw off your balance when standing on the board.

This backpack is ideal for active paddlers who tackle rough river corridors, windy bays, or wet portages. It is overkill for casual flatwater paddlers who only carry a car key and a water bottle for an hour-long float.

Waterproof Phone Case – JOTO Universal Pouch

Your smartphone is your lifeline for navigation, emergency calls, and capturing photos, but water damage can ruin a trip instantly. A reliable, low-profile waterproof pouch allows you to use your touch screen and camera right through the plastic while keeping the device secure. It prevents the absolute disaster of a dropped phone sinking into the lake or ocean.

The JOTO Universal Pouch is a budget-friendly powerhouse featuring a simple, highly secure snap-and-lock seal. The crystal-clear scratch-resistant windows on both sides allow for distortion-free photos and video recording. It also includes a durable lanyard, keeping your phone secured to your body even during a hard fall.

• Waterproof Rating: IPX8 certified (up to 100 feet)
• Compatibility: Fits smartphones up to 7 inches diagonally
• Best Uses: Photography, emergency communication, and keycard storage
• Key Feature: Clear window design with high touch sensitivity

Before trusting your phone to the water, always perform a quick paper towel test at home to verify the seal’s integrity. Be aware that touchscreens will not register touch inputs underwater due to water pressure, so use your phone’s physical volume buttons to snap photos. Additionally, bulky heavy-duty phone cases may need to be removed to fit inside the pouch.

This pouch is a must-have for every recreational paddler who brings a phone on the water. It is not suitable for those looking to store bulky items like wallets or key rings alongside their phone, as stretching the plastic can compromise the seal.

Protective Hard Case – Pelican 1060 Micro Case

Soft dry bags are great for flexible items, but delicate electronics, expensive key fobs, and medical supplies need crushproof protection. A hard-sided utility case prevents your gear from being crushed underfoot or smashed against the board when climbing back on after a fall. It provides a rigid, impact-resistant sanctuary for your most fragile valuables.

The Pelican 1060 Micro Case stands out with its legendary polycarbonate construction and an automatic pressure equalization valve. A thick rubber liner doubles as an O-ring seal, keeping dust, dirt, and water completely out. The stainless steel hardware ensures long-term resistance to salt corrosion, making it a staple for coastal paddlers.

• Interior Dimensions: 8.25″ x 4.25″ x 2.25″
• Material: High-impact polycarbonate
• Best Uses: Key fobs, action cameras, wallets, and emergency medication
• Key Feature: Automatic pressure equalization valve

Note that this case is water-resistant and can handle brief submersions, but it is not rated for deep, prolonged diving. It also sinks if overloaded with heavy metal items, so attaching a small foam float or securing it to your board’s bungee system is highly recommended. Regularly clean the rubber O-ring seal to prevent sand grains from breaking the watertight barrier.

This case is perfect for paddlers carrying expensive key fobs, action cameras, or medication. It is not meant for those needing to store large items like towels, changes of clothing, or bulk rations.

Waterproof Duffel Bag – Yeti Panga 50 Dry Duffel

For overnight camping trips or gear-heavy expeditions, a standard dry bag simply lacks the capacity and ease of access you need. A waterproof duffel bag sits securely on the deck of your SUP, offering a wide-mouth opening so you can find your gear without dumping everything out. It protects sleeping bags, dry clothing, and camp stoves from the harshest downpours and wave washes.

The Yeti Panga 50 Dry Duffel is a bombproof option featuring a high-density nylon ThickSkin shell and a fully submersible Hydrolok Zipper. This zipper creates an airtight, watertight seal that keeps contents bone-dry even when the bag is dragged through rapids. The DryHaul straps allow you to carry it comfortably as a backpack during portages or dock walks.

• Capacity: 50 Liters
• Waterproof Rating: IPX7 (fully submersible)
• Best Uses: Multi-day touring, camping gear, and heavy expedition supplies
• Key Feature: Submersible Hydrolok zipper and puncture-resistant shell

The airtight zipper requires a firm, steady pull to operate and must be fully closed to maintain its waterproof rating; a partially open zipper will let water in instantly. It is also a premium, heavy-duty piece of gear that represents a significant financial investment. Regular maintenance using the included zipper lubricant is required to keep the slide moving smoothly.

This duffel is built for serious touring paddlers, overnight campers, and those navigating rough, exposed waters. It is unnecessary for casual afternoon paddlers who only need to keep a towel dry on calm lakes.

Waterproof Waist Pack – Patagonia Guidewater Hip Pack

If you prefer to keep your board clean and clutter-free, a waterproof waist pack is the perfect alternative to deck-mounted bags. It keeps your hands free, doesn’t interfere with your paddling stroke, and ensures your critical safety gear stays with you if you get separated from your board. It is the ultimate hands-free storage solution for active, mobile paddlers.

The Patagonia Guidewater Hip Pack is a fully submersible pack made from tough, recycled nylon with a polyurethane coating. It features a heavy-duty TIZIP zipper that seals out water completely, even during prolonged submersion. The internal pocket arrangement organizes small items, while the external lash points let you attach a water bottle or a net.

• Capacity: 9 Liters
• Waterproof Rating: IPX7 certified
• Best Uses: Fishing gear, small cameras, snacks, and personal safety items
• Key Feature: Fully submersible TIZIP zipper and breathable waist belt

When wearing a waist pack, ensure it is adjusted snugly to your hips so it does not shift or slide while you twist your torso to paddle. The zipper can be stiff initially, so using the provided lubricant on the docking end is essential for smooth operation. Remember that a waist pack adds bulk to your midsection, which can make climbing back onto your board slightly more challenging.

This hip pack is ideal for paddle anglers, photographers, and long-distance touring paddlers who need constant access to gear. It is not the right choice for casual paddlers who find wearing gear around their waist uncomfortable or restrictive.

Waterproof Key Case – Fidlock Hermetic Dry Bag Multi

Modern electronic car keys are incredibly sensitive to water damage, and replacing them can cost hundreds of dollars. Leaving them hidden on your car tire is a theft risk, so carrying them securely on the water is your best option. A dedicated key case must offer absolute waterproof security in a compact, unobtrusive package.

The Fidlock Hermetic Dry Bag Multi uses an innovative, patented magnetic-mechanical closure that seals automatically when released. This magnetic seal provides IPX8 protection up to 100 feet without the need for fussy ziplocks, snaps, or rolls. The clear, touch-compatible material allows you to operate key fobs or small devices without removing them from the bag.

• Waterproof Rating: IPX8 (submersible up to 100 feet)
• Closure Type: Magnetic self-sealing closure
• Best Uses: Electronic car keys, credit cards, cash, and licensing documents
• Key Feature: Foolproof automatic sealing technology

While the magnetic closure is foolproof, always ensure no sand or debris is stuck to the magnetic strip, as this can break the seal. This case is designed strictly for small items, so do not try to force large keyrings or multi-tools inside. It can be worn around the neck with the included strap or tucked inside a life jacket pocket.

This case is the perfect insurance policy for solo paddlers who must carry electronic car keys and credit cards on the water. It is not suitable for those trying to store bulky keychains, sunglasses, or pocket knives.

Roll-Top Dry Sack – Sea to Summit Big River Dry Bag

The classic roll-top dry sack is the undisputed workhorse of water recreation, offering flexible, lightweight, and scalable storage. It organizes your gear into manageable bundles that can be easily lashed under deck bungees or stuffed into larger packs. It is the foundation of any solid SUP storage setup, handling everything from spare layers to lunch.

The Sea to Summit Big River Dry Bag is built from heavy-duty nylon with double-stitched, reinforced, and tape-sealed seams. It features multiple hypalon lash loops on the sides, making it incredibly easy to secure directly to your board’s deck lines or D-rings. The roll-top closure uses field-replaceable buckles, so a broken buckle won’t ruin your trip.

• Capacity Options: 5L to 65L
• Material: Heavy-duty 420D nylon
• Best Uses: Storing extra layers, sleeping bags, stoves, and camp food
• Key Feature: Multiple hypalon lash loops for secure mounting

To achieve a truly waterproof seal, you must roll the stiffened top strip at least three times before buckling; simply folding it once or twice will let water seep in. Avoid packing sharp objects like tent stakes or fishing hooks directly against the bag’s walls without protection, as they can puncture the fabric.

This dry sack is perfect for paddlers of all skill levels who need reliable, rugged, and adaptable storage for clothing and gear. It is not recommended for highly delicate electronics that require hard-sided crush protection.

How to Properly Secure Dry Bags to Your Paddleboard

Having the best waterproof gear means nothing if a sudden wave sweeps your bags off the deck and into the currents. Properly securing your dry bags keeps your gear attached to the board and maintains the board’s balance and stability. An unsecured bag acts like a sail in high winds and can easily upset your center of gravity.

Most paddleboards come equipped with a front bungee deck rigging system or pre-installed D-ring attachment points. Thread your dry bag’s straps or built-in lash loops directly through the board’s bungees, or use marine-grade carabiners to clip the bag to the D-rings. For larger bags, run a heavy-duty cam strap over the top of the bag and secure it tightly to the board’s tie-down points.

Always position heavier items as close to the center of the board and as low to the deck as possible to maintain stability. Packing heavy gear too far forward on the nose will cause the board to plow through water, while packing it too far back will drag the tail. Test your board’s trim in shallow water before heading out on a long paddle.

Maintaining Waterproof Zippers and Gaskets Over Time

Waterproof gear is an investment, and like any marine equipment, it requires regular maintenance to perform reliably season after season. Saltwater, sand, and UV rays are the natural enemies of waterproof zippers and rubber gaskets, causing them to dry out, crack, or jam. Proper post-trip care prevents catastrophic seal failures when you are miles from shore.

After every trip, especially in saltwater, thoroughly rinse all zippers, seals, and buckles with fresh water to remove salt crust and abrasive sand. For waterproof zippers, apply a thin coat of silicone-based zipper lubricant or beeswax to the teeth and slide the zipper back and forth to distribute it. For rubber O-rings on hard cases, wipe them down with a damp cloth and apply a light coating of silicone grease to keep the rubber supple.

Store your dry bags and hard cases partially open in a cool, dry, and well-ventilated area away from direct sunlight. Storing them fully sealed can trap residual moisture, leading to mold, mildew, and unpleasant odors that degrade the interior linings. Regularly inspect the seams and heat welds for any signs of peeling or delamination before your first seasonal outing.

How to Choose the Right Gear Capacity for Your Tour

Choosing the correct storage capacity is a balancing act between bringing what you need and keeping your paddleboard light and maneuverable. Overloading your board makes paddling exhausting and compromises your stability in choppy water. Conversely, under-packing can leave you cold, wet, and without critical safety gear if the weather suddenly turns.

For short, recreational paddle trips lasting under two hours, a 5L to 10L capacity is plenty for your phone, keys, sunscreen, and a windbreaker. If you are heading out for a full-day tour, upgrade to a 20L to 30L setup to accommodate extra water, lunch, a small first-aid kit, and thermal layers. For overnight or multi-day SUP camping expeditions, you will need a combination of bags totaling 50L to 90L distributed across the nose and tail.

Keep a detailed gear list and pack your bags at home first to see how everything fits and weighs. Remember that bulkier, lighter items like sleeping bags should go in larger roll-tops, while dense, heavy items should be split into smaller, manageable dry sacks. This modular approach makes balancing your board’s load much easier on the water.

Conclusion

Keeping your gear dry on a stand up paddleboard is not just about convenience; it is a fundamental aspect of water safety and trip enjoyment. By investing in the right combination of rugged dry bags, protective hard cases, and reliable phone pouches, you can focus on the water ahead rather than worrying about what is getting wet. Secure your gear, maintain your seals, and head out with the peace of mind that only true waterproof protection can provide.
