Camping in the shadow of Half Dome is rendered sweeter when youâve seen the view from the top, and weâve developed this performance pack to get you there. The Endura 50-Liter Backpack features our most advanced suite of technical innovation: Omni-Shield advanced repellency keeps the packâs contents dry, while an integrated rain fly engages during serious downpours, and itâs thoughtfully designed to still allow access to water-bottle pockets. Our all-new Backdraft Aerating Suspension utilizes lightweight frames with a tensioned backpanel to lift the packâs load slightly off your back, allowing fresh air to pass through. Plus, all contact points feature breathable mesh and side vents to further eliminate hotspots. The exceptionally comfortable, 19mm-thick Velocity L.O.A.D. straps are made from two layers of ultra-light Techlite foam-a softer one on the inside for next-to-body comfort and a more rigid one on the outside for durability. The Techlite is molded around super-strong mesh inserts for unprecedented breathability and featherweight strength. The Enduraâs Silverback reflective lining provides a bright interior so you can see your gear better for grabbing things on the fly. Two different entrees (front and top) make packing a breeze, while a buffet of aptly placed pockets hold everything from first aid kits to GPS units perfectly. Ample compression and stabilizing straps keep your load right where it should be. FEATURES: Fabric: 420 D velocity nylon, 70D SilverBack nylon diamond ripstop.
