This handy Compression Strap, compatible with the Granite and Challenger backpacks, is designed to secure gear like skis, ropes and poles to the side of your backpack. The straps can also be used to reduce the volume of your bag when not fully loaded and stop items from rattling around, whether you’re climbing or boot packing up or gliding back down the mountain. The Compression Strap is an easy way to keep your gear safe and accessible.
