Precautions for electronic devices

Electronic devices are fragile and valuable. We recommend doubling up their protection by putting phones in waterproof pouches inside dry bags. Cameras can be put in a small dry bag (5 L or 10 L) placed inside a large dry bag (30 L, 40 L, 60 L). Ensure your bags are correctly closed and regularly check water resistance before your sessions using a paper towel. Do not swim with the bag or immerse it underwater.

Fastening system

To ensure good water resistance: 1/ Carefully roll down the top of the bag 5 times, by tightening the folds across the thickness of the strap. 2/ Fasten the center buckles. 3/ Fasten the side buckles. Leave some air in the bag. The bag should appear inflated once closed: this makes it more watertight and allows it to float if dropped in the water.


Various eco-design innovations have allowed a 62% reduction in CO2 impact of the 40 L bag. - The reduction in the number of manufacturing steps has a direct consequence on the decline in necessary resources (water and fuel). - Using specific non-dyed textiles. The color is put directly into the outer PVC layer. The dye is one of the most polluting textile processes, so avoiding this step makes it possible to save lots of CO2.

Technical dimensions

Bag dimensions when full and closed: Height: 27.6" Diameter: 11.8" Usable volume: 40 L Weight when empty: 1.7 lbs


The 5 L and 10 L bags can be placed inside the 30 L, 40 L, and 60 L bags to double the waterproof protection of sensitive objects and to separate belongings.



Product testing

Water resistance tests: Test 1: "puddle of water" The bag is resistant to shallow immersion for 8 hours in 4" of water. This test corresponds to a bag floating in a water-filled boat or to a brief fall into the water. Test 2: "shower" The bag is resistant to a shower of 450 L/m²/h lasting 2 hours. This test corresponds to heavy rains or splashes from waves.

Storage instructions

Rinse with clean water and dry the product before storing for long periods to keep the materials in good condition.
