Dont waste money in expensive bags who doesnt work.

Go to an army surpluss shop, one of those army items, and buy a duffle bag, they are long and looks like a sack, they sell all types of them, black, military green, and no zipers just a simple design of holes and hook.

They sell the navy version wich is made of plastic material who keeps the water inside or outside.

Just a military large sack, thats the best design.
