The Mountain Hardwear Scrambler 35L Backpack is a durable daypack for climbers and ambitious hikers or an overnight pack for ultralight backpackers. Fully overhauled for better support stability and abrasion resistance it features a TPU-coated nylon ripstop that's ultra-durable and waterproof to protect our gear lunch and layers from the elements. The contoured and ventilated back panel keeps us comfortable while the supportive shoulder straps and hip belt compression straps and sternum straps secure a close-to-body fit and support for scrambly approaches and technical trails. If we're counting ounces we can remove the hip belt straps lid and frame sheet for minimalist missions--or carry extra gear with the full-length daisy chains internal gear loop and forward-access gear loop which keeps our clipped gear easily accessible. Like most of Mountain Hardwear's impressive lineup it's made for alpine terrain and serious outdoor pursuits.
