If you've never hiked with trekking poles, it's about time you tried. Made from Helinox's proprietary alloy, the Causeway Series Trekking Poles will make a believer out of you with a design that's light, sturdy, and will save your knees during steep and rocky descents. The Causeway series is available in either a groove locking system or a dual locking lever design. Both are designed to handle heavy loads and are suitable for both gear intensive treks and single day peak bagging hikes. And when you need some extra cushion in steep and demanding terrain, The Groove Lock Shock Absorber option utilizes a mechanical engagement system to increase the load capacity of the poles.
