Spend weekends alpine climbing on Lone Peak and in the Wind River Range with Millet's Ubic 50 10 Backpack. Its 50L main compartment extends to offer an additional 10L capacity for backpacking and alpine gear. Millet's Adjustable Foam Lighter Back panel moves cushy, breathable 3D mesh up and down the back for a precise fit. The Variloop System stores snowshoes, alpine equipment, and even skis. The Ubic also features hydration compatibility for your own reservoir, and there's a rain cover to protect your gear from moisture. The removable top lid has two zippered pockets, and the zippered bottom compartment accommodates your sleeping bag. There are carry loops for ice axes and trekking poles, a stretchy zippered front pocket, two side pockets, and multiple zippered pockets for topos, maps, headlamps, and valuables.
