Hello, im going to sail on a friend's catamaran for 1 month soon. And i want to buy a waterproof sleeve/pouch to put my laptop, e-reader and passport. Its been harder than i tought to find something. I found these (https://imgur.com/a/Bn7zXFX) but i dont need 3 and they seem of bad quality... I also looked waterproof map holder and found this one from sea to summit but its pretty expensive. I just want a waterproof pouch like those small for phones, but the size of my small laptop (A4 paper). I also tried to look some "waterproof document holder" but its always big huge things. I want to also use it while backpacking so i dont want a super heavy thing. What do you use, sailors of reddit ? Thanks
