From fast ascents to remote traverses, MSR DynaLock Ascent Poles keep snowshoers, mountaineers and splitboarders moving quickly on mountain objectives. Built of Kevlar-reinforced carbon fiber, these ultralight poles feature a quick-deploy design, and their tiny collapsed size fits inside alpine packs and travel bags. Equipped with our DynaLock mechanism, they offer 20 cm of length adjustability, and the ability to tighten the clamping force on the fly for no-slip security—perfect whether you're bagging volcanoes or pushing hard from first light to last. Available in two sizes; Small size is 100-120 cm (39.4-47 inches) and collapses to 36.2 cm (14.25 inches), Large size is 120-140 cm (47.2-55 inches) and collapses to 44.5 cm (17.5 inches).
