You've been planning and day-dreaming about this trip all year. Flights are booked, maps are studied, flies are tied, and gear has been carefully selected. Now you just need to get there and keep it all safe and dry on the water. A favorite among our friends in Alaska, the Wind River Roll-Top Backpack has ample space to transport gear through the airports and into the wild with comfort. We improved this Fishpond classic with adding a thermoformed back panel and adjustable hip belt so you'll have this pack for the long-haul.900D TPU coated NewStream fabricOne set of Lariat gear straps (included) that can be positioned on left or right sideRoll top waterproof main body compartmentFront stretch mesh pocket with zipper closureLightweight foam shoulder strap, hip belt, and molded back panelAdjustable and removable lumbar support strapCoated webbing haul handleInterior organization with removable zippered pocketHypalon attachment points on shoulder straps for two-way radios or GPS systemsCompatible with Thunderhead Chest Pack, Canyon Creek Chest Pack, Sagebrush Pro Mesh Vest front panel, and Cross-Current Chest Pack.
