Why We Like The Lithium Speed 20L Backpack

Mammut's Lithium Speed 20 Backpack is an all-around mountain player, as long as the trail run, multi-pitch climb, or hike is a fast one. Its Contact Vent system pairs a well-ventilated, cushy back panel with padded shoulder straps and waist belt to ensure comfort on the ascent. The Lithium Speed is hydration-compatible so we can keep our reservoir accessible, and it carries our trekking pole when the ascent gets steep or even vertical. There are plenty of pockets, large and small, to organize our valuables, topo information, and lunch intelligently, so we can skip the rummaging and get back to the trail faster.
