Our supreme offering, the feature-rich SealLine Discovery Deck Waterproof Dry Bag with PurgeAir delivers resolute waterproof protection from day trips to expeditions, whether in a boat, slung over a shoulder with the shoulder strap, or lashed to a SUP board, truck, or burro via the multiple lash points. The Discovery Deck's PurgeAir valve helps the bag compress further once it's been sealed for superior packing versatility. Adjustable carry strap and multiple lash points make it easy to carry or anchor the bag. Made with light-colored or semi-translucent interiors significantly ease identification of contents within, and its DrySeal roll-top closure makes it easier and more intuitive to achieve an optimal seal.
