LEKI's Sherpa Collection consists of the most versatile poles for trekking, skiing, and mountaineering year-round, and the Sherpa FX.One Carbon is the only option that's non-adjustable and collapsible. They also boast a unique hybrid construction combining carbon and aluminum for the best balance of durability and an ultralight weight. LEKI's Aergon Air grip gives a soft but grippy feel, and the grip extends down the upper section for easier use on technical trails and steep switchbacks.
