Always says dry

Cheaper in comparison to anywhere else by hundreds, using to carry items while on motorcycle and has always stayed completely dry

Not waterproof!! Waste of money!!

Do not buy it, it is not waterproof! Put 1Kg in it and it will sink. You will obviously put things like your mobile, keys, maybe dry clothes, maybe food in it. Things that eventually creates a bit weight, use it empty would be pointless, so the weight will drop it down a bit. But that's enough to release all the air and eventually the water comes in.

Really practical..

...large so can hold a lot. Actually using it for my son's rugby gear - keeps everything dry while he is playing and the muck just wipes off!

Leaky Waterproof Dry Bag

I took this along for a coast hike and a stream hike. And each time the bag would leak with water and get everything wet inside despite it claiming to be a waterproof. My friends dry bags from Watersport HK don't have this issue at all. I think it is due to the poor design as the clips can't lock in the center. It can only be locked on the sides which is easier for water to leak in. I really can't use this bag since it always leaks and destroy my stuff. Please let me know how I can get a refund for this bag!

Hello Caleb,

Firstly, we apologise for the uncomfortable product experience created by our product.

We take great care to ensure that important matters such as this are properly managed. 

The issue has been already passed to the production line and we will keep striving for the best on the quality issue.

In addition, to prevent the water get into the bag, our France Team made a tutorial video to assist you in sealing the bag in the best way. Hope it helps.

Here are the instructions:

1. Leave some air inside

2. Follow the 1, 2, 3 logos to fold it tightly before buckle up

3. Ensure the bag is filled with a certain volume of air to protect the bag from the water 

4. Do not put the bag in a long period of immersion 

Once again, we would like to apologise for the inconvenience created by the related product.

You are welcome to visit any of our stores to exchange or refund in any of our stores.

Additional Product Information


Main fabric

  • 60% Polyester cationic
  • 40% Thermoplastic polyurethane

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 closed and check water resistance regularly before your session using a paper towel.

Fastening system

To ensure good water resistance: 1 / roll the top of the bag over carefully 5 times, folding tightly over the width of the strap 2/ fasten the central buckle 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.


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.

Technical dimensions

Dimensions of filled and closed bag: Height: 24.8" Diameter: 10.2" Usable volume: 30 L Empty weight: 15.9 oz



Product testing
