Mountain Hardwear constructed the Scrambler 25L Backpack from 4-layer Dimension-Polyant to seal out moisture fend off snagging branches and rough surfaces on the approach and ultimately protect all our gear within. The padded base helps the pack stand vertically to load gear easily while waist and sternum straps stabilize the pack for a comfy carry. A variety of attachment points include daisy chains an internal gear loop and the Forward-Access system which lets us reach clipped gear without taking off the pack.
