The Mountain 35 is the new larger version of the North Face classic Mountain 25 mountaineering tent. This expedition standard packs a ton of weather protection while offering ample room for up to three adventurers. This rugged 4-season tent weighs in at ten pounds, has two vestibules, dual doors, and high low ventilation to keep condensation to a minimum. If you are headed into the backcountry come winter you deserve an all-mountain shelter such as the new Mountain 35.
