If your knees ache after long and rocky descents, be sure to bring the Komperdell Explorer Compact Power Lock Trekking Poles along on your next hike. Their solid aluminum shaft helps reduce the amount of weight on your legs and knees, and it features a Power Lock 3. 0 adjustability mechanism so you can easily dial in the perfect fit when you're side-hilling, climbing, or descending. An upgrade over previous versions, Power Lock 3. 0 sports a new flap-mechanism that's forged of anodized aluminum to give it considerably improved holding power while also adding a slimmer look. Their contoured grips are designed with comfort in mind, and are equipped with an extended foam grip so you can choke up on them during steep ascents.
