Combining the convenience of a duffle bag with the best waterproof protection we offer, the Zip Duffle is built with the same submersible YKK zippers used on the finest dry suits. The zipper runs diagonally across the top for quick access and has a vinyl flap for added protection. Webbing handles stay together with a Velcro® grip, and convenient end handles (on 75L) make ship-to-shore transfer easy.
