SealLine Zip Duffle 40L - Black - 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. Its low-profile shape is great for close quarters; the Zip Duffle 40 even fits through the back hatch of most kayaks. Also great for motorcycle touring and riding on outside luggage racks regardless of the weather. Available in two sizes.
