Daypacks have never had so much innovation as the Columbia Treadlite 22 Backpack does. The Treadlite 16 Backpack features Columbia's most advanced suite of technical innovations like Omni-Shield advanced repellency which keeps the pack's contents dry. The all-new Backdraft Aerating Suspension utilizes lightweight aluminum frames with a tensioned backpanel to lift the pack's 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 Techlite's Silverback reflective lining provides a bright interior so you can see your gear better for grabbing things on the fly. The Techlite is loaded from the top, while a plethora of smartly 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 and stretch woven water bottle pockets keep hydration close.
