The bag is very sturdy and is certainly every rain. But in a test where I have held underwater, penetrates with small amounts of water in the bag. Therefore, not necessarily suitable for an exchange passage in the ocean. The price is way too expensive product just for this Made in China. I would buy it for a good 5, but not for nearly 10 degrees. I recommend just to plastic bags with closure Ziploc- to buy, which are significantly cheaper than alternative. I take this pocket only for important documents or other small appliances.
But still worth a recommendation for spending a little more money are ready.
