How to Pack a Dry Bag for Kayaking and Paddleboarding

A dry bag can make it easier to organize spare clothes and other gear on a paddling trip, but the name does not mean every bag protects every item in every situation. Its closure, material, condition and intended use all matter. Before going on the water, read the instructions for your exact bag and plan how you will carry the things you need to reach quickly.

This checklist focuses on packing a roll-top bag. It does not replace local water-safety guidance, a suitable flotation device or a reliable means of calling for help.

Choose a bag for the trip

Consider where the bag will ride: inside a kayak compartment, secured to a deck, or carried separately on a paddleboard. Measure the available space and check how the filled bag fits. A large bag may hold everything but can be difficult to place or retrieve; several smaller bags may make it easier to separate items.

Compare the maker's intended use, closure and water-resistance limitations. A lightweight sack intended to organize gear inside a backpack is not automatically suitable for exposed use on a boat. Sea to Summit's dry-bag guidance explains that roll-top closures can admit water under sufficient submersion and pressure. Check the rating and instructions of your own product rather than assuming it is submersible.

Choose a size that leaves enough space for the closure to be folded and fastened as instructed. A bag packed to its very top can prevent the closure from working properly.

Inspect it before packing

Look over the fabric, seams, closure strip, buckle and attachment points. Check for punctures, abrasion, cracks or damage to any coating. Follow the manufacturer's inspection and repair instructions. If the bag is damaged or you cannot close it properly, do not depend on it to protect your gear.

Keep sand, grit and debris out of the closure. A contaminated or twisted top can make an even seal difficult. If the bag is wet inside from a previous trip, dry it before adding clothing or other items that need to remain dry.

Separate and organize the contents

Pack a dry change of clothes in a separate inner bag or pouch so it stays organized when you open the main bag. Put softer, lighter items where they are easy to remove, and protect the bag from sharp objects. Place keys or small accessories in a labeled pouch rather than letting them settle loose at the bottom.

Keep anything needed urgently in a suitable, accessible place. The RNLI's paddleboarding guidance recommends carrying a phone in a waterproof pouch on your person so it can be reached in an emergency. Do not make a bag attached to the board your only way to access a communication device.

Pack electronics only in protection appropriate to their exposure and value. Sea to Summit warns that roll-top bags are not guaranteed to protect electronics during heavy submersion; it describes double-bagging and suitable sealed hard cases as additional options. Follow the chosen case maker's instructions and do not promise complete protection.

Close the top as directed

Smooth the top and remove excess air as the bag maker recommends. Keep the opening clear of fabric, straps and grit. Fold or roll the closure in the specified direction and secure the buckle without twisting it.

NRS's closure instructions advise folding the top of its described bag at least three times before clipping it shut. Other products can have different closure systems, so use the instructions attached to your particular model. Leave enough material above the contents to complete all required folds.

After closing, inspect the buckle and closure. Do not squeeze a bag aggressively to test it while valuable electronics are inside. If you need to evaluate an unfamiliar bag, follow the maker's testing guidance with expendable contents before relying on it for a trip.

Secure it without creating an entanglement hazard

Check the craft's instructions and use a suitable attachment point for the conditions. The bag should not interfere with your paddling, balance, exit or access to safety equipment. Keep loose straps short and controlled, and never improvise a connection to your body that could trap you.

A dry bag is not a flotation device. Wear the appropriate personal flotation equipment for the activity and conditions, and follow local rules and instruction. Consider weather, wind, tide, water temperature and your experience before launching.

Place the bag so its closure is protected from direct wave action where the craft and the bag instructions allow. NRS suggests orienting the fold away from wave action when stowing its described bags. Do not assume a secured bag will stay dry after prolonged immersion.

Rinse, dry and store

After use, follow the care label. NRS recommends periodic fresh-water rinsing and air drying for its dry bags. Open the bag fully and let both the inside and outside dry before storage; trapped moisture can affect the next load of gear.

Inspect the closure and seams again, then store the bag as directed and away from prolonged sunlight. Record any damage and repair or replace the bag according to its maker's guidance. Browse the Watersport Equipments journal for more equipment preparation guides.

Frequently asked questions

Is a roll-top dry bag safe to submerge?

Not all are designed for submersion. Check the specific product rating and instructions; water can enter through a roll-top closure under pressure.

Can I put my emergency phone inside the bag on my board?

Keep your means of calling for help accessible on your person in protection appropriate for the conditions. Consult local safety guidance and your case maker's instructions.

How many folds should I make?

Follow the exact bag maker's directions and leave enough room to close the bag correctly. Closure designs vary.
