I have used it rafting and kayaking. waterproof and great.
Just got our Kodiak Dry Bags (10 & 20 Liters). When I unwrapped them from their boxes I thought 'gee-whiz these are awfully big'. But after seeing how they work you quickly realize they aren't as big as they first appear which is great because that first impression was "I didn't want something that big".
We took our dry bags on a Kayak trip on the Hudson this weekend. We stored our cameras, wallets, cell phones, etc in them. Between the rough chop on the Hudson and the required water fights afterwards, I found myself drenched from head to toe but the contents of the dry bags never saw a drop of water.
The bags fold up nicely and store away in a drawer bottom taking nearly no room. I'm very satisfied with the purchase.
