Collection: Waterproof Backpacks

Yes, all of our waterproof backpacks are designed to be fully waterproof. They feature high-frequency welded seams and roll-top sealing systems, ensuring complete protection from water, sand, and dirt. Our range of waterproof backpacks are also suitable for quick submersion, providing you with maximum protection during your outdoor adventures.

Our weatherproof backpacks are designed to be foul weather and spray proof, offering excellent protection against rain, dirt, and dust. However, they are not fully waterproof like our dedicated waterproof backpacks. While they provide great protection in most weather conditions, they are not suitable for full submersion in water.

If you need a completely waterproof backpack, please check our Waterproof Backpack Collection for backpacks with full submersion protection.

To learn more about the waterproof ratings and the Ingress Protection (IP) rating system for all our products, please visit our Waterproof Ratings page.

"Quick submersion" refers to our backpacks' ability to withstand brief periods of submersion in water without allowing water to penetrate. This means they can handle situations like accidental drops in water or short immersion, but they are not designed for prolonged submersion. For complete protection, we recommend ensuring the roll-top seal is securely fastened before exposing the backpack to water.

The Coolers Dry Bags include an external weatherproof zip
pocket with an IP65 rating.

• The main compartment (IP66) is designed for quick submersion and will protect contents if the bag is briefly dropped in water.
• The weatherproof zip pocket (IP65) is foul weather and spray proof, meaning it can handle rain, splashes, and spray—but it is not submersible. Water may enter the zip pocket if the bag is fully submerged.

Tip: Store valuables, electronics, or water-sensitive items inside the main roll-top compartment rather than the outer zip pocket when in wet or unpredictable conditions.

Yes, all of our IP66-rated waterproof backpacks are suitable for swimming. However, it's important to avoid prolonged submersion and to ensure the backpack is sealed correctly, as per the instructions. Keeping the roll-top seal as high above the waterline as possible will help maintain waterproof protection and keep your belongings dry.

Our waterproof backpcks are sealed using high-frequency welded seams and a roll-top sealing system. The roll-top design allows for a secure closure by rolling down the top of the bag several times and fastening it with a clip or buckle. This creates a tight, waterproof seal that prevents water from entering the bag, ensuring your gear stays dry even in wet conditions.

All of our 20L and 30L waterproof backpacks are designed to fit within standard cabin carry-on limits, making them ideal for air travel.

Our larger 45L waterproof backpack also comes close to most airline size restrictions, measuring 49cm (H) x 33cm (W) x 28cm (D). While the depth slightly exceeds some airline limits, its soft, flexible design often allows it to fit into overhead compartments—especially when not fully packed.

Since cabin bag policies can vary depending on the airline and your fare type, we always recommend checking with your airline before travelling. Thanks to their soft structure, our backpacks are often accepted as cabin luggage—especially when not fully packed.
