Dry bag with roll top. Made from ultra-strong nylon 260D. Incorporates a window. The material is slippery making it easy to slide it down the hatches, and to move it around inside the kayak.

The 12 and 24-liter versions incorporate a valve for easy compression while rolling. The diameters of 6 to 7,8″ make them fit down any round hatch on most kayaks.
