The Endura 50 features the most advanced technical innovation: outer shell keeps the contents of the pack dry, while an integrated rain fly activates during severe rain, and is carefully engineered to still allow access to the water- pockets Bottle. Our new Backdraft Aerate suspension uses lightweight frames with a tensioned backpanel to lift the cargo pack slightly off, allowing cool air to pass through your back. Additionally, all contact points feature breathable mesh and side vents to further remove access points. The exceptionally comfortable, 19mm thick Velocity. Straps are made of two layers of ultralight Techlite foam, one softer on the inside for next-to-body comfort and stiffer on the outside for durability. The TechLite is molded around Super Tough with mesh inserts for unprecedented breathability and FEATHERWEIGHT strength. The Silverback Endura's reflective interior lining provides a brighter look so you can see your gear better for grabbing things on the go. Two different entrees (front and top) make boxes a breeze, while a 'buffet' with pockets neatly placed to store everything from first aid kits to GPS units. Wide compression and stabilization straps keep your load right where it needs to be.
