Sea To Summit eVAC 3-65L Dry Sack Grey, 65L

The Sea-to-Summit eVAC Dry Bag uses a waterproof and breathable eVENT fabric to keep your gear bone dry. It's like a compression sack, but the design allows you to simply push excess air out the bottom eVENT panel as you roll down the top. No more compression straps, and no more busted seams from reefing too hard on said straps. Plus, the base is oval, so it won't roll off the deck and float down the river without you.
