Does this dry bag float? Yes! Our dry bags are meant to float and stay a top of water so you’ll never lose sight of your gear during kayak flips, etc. When you roll the top of your dry bag down, there should be a little bit of air in it giving it a "inflated" type of feel so it will always float to the surface if lost. However, because our dry bags are meant to float, they are not fully submersible and should never be submerged underwater for longer than 5-10 seconds.
