Here in the Pacific Northwest, we take waterproofing seriously. The Hood is the only waterproof, quick-access tank bag on the market we've seen. There are no zippers and no roll-tops to unfurl. Just unclip the buckle, flip the lid, and you’re in. It’s the easiest-access waterproof tank bag we’ve used. It includes two handy internal organizers for little things like charging cables and earplugs.
