not bad but little better for the same price

The price is great. The bag is minimalist and seems quite sturdy. On the other hand, what a shame not to have reversed one of the 2 clipped attachments (male/female & female/male). When the bag is full and you can no longer reach the clips on the side, the bag remains open. It's a shame, we lose volume and it was free to sew the asymmetrical fasteners to close the bag from above...just maybe a bit more complex on the manufacturing line (and then again...). Competition also reverses the bindings. I wonder why you made this choice?

Large capacity waterproof bag

Very good capacity to store everything. Be careful to leave some air, otherwise the bag will no longer be waterproof.

Very good product ,I bought it for cycle touring,it perfectly fits back pannier.

Sailing bag

Very good material, the bag is clearly visible in the water and tight.

Does the job

It's big enough and durable and can also land in the lake without the water getting in, at least for a short time. (I capsized the boat.

Too early

I didn't have a chance to test it in open water. Good for shopping in the rain. Rihanemö should only be put in with double packaging, because it mercilessly takes over the stinky plastic smell of the bag.

Main fabric: 100.0% Polyvinyl Chloride

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 NEITHER 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 centre 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 55 % 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 colour 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” (70 cm)Diameter: 11.8” (30 cm)Usable volume: 40 LWeight when empty: 26.6oz (755 g)


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 WATERThe bag is resistant to shallow immersion for 8 hours in 10 cm of water.This test corresponds to a bag floating in a water-filled boat or to a brief fall into the water.TEST 2: SHOWERThe bag is resistant to a shower of 450 L/m²/h lasting 2 hours.This test corresponds to heavy rains or splashes from waves.
