Does anyone know where to buy the waterproof cases to hold money, cards, passport, etc.? The hardsided ones that you buy at places like waterparks, seem to leak.
Find a dive or kayaking type shop locally and look for an otterbox or drypak. They work the best, but drypaks are usually softsided. I think mec.ca has some but I don't know if they deliver outside Canada.
I have seen these at Walmart in the camping section. Otterbox is a brand name and of very high quality, I do not recall what the brand name was on the Walmart ones
If you're looking for a soft case, I just got 2 Aquapac Keymasters for our upcoming trip. I ordered mine on Amazon, but I've also seen them on LL Bean (although they are backordered right now or I would have gotten them there), eBags, and Aquapac also has its own website. They were about $15 a piece, and apparently they work well (I don't think LL Bean would carry them if they didn't). I tried mine out and there is plenty of room for a couple credit cards/room keys, some cash, car key, etc. Hope this helps!
We got waterproof wallets at Walmart last year (think they were only about $2). They are the perfect size for credit cards, room keys, and folded cash. One side ziplocs. We have never had trouble with them leaking. I think they were in the camping section.
