High-terrain cross country skiing calls for a lightweight pole designed with rugged terrain in mind. Good thing Swix created the Mountain Extreme Ski Pole just for that purpose. An update on traditional, deep-powder nordic poles, the Extreme has an extra wide leather basket for ample flotation in the deep and a near-bulletproof carbon shaft that's low on weight and high on strength. Even when you wear a pair of heavy down gloves, you'll find that the extra-long wrist straps secure easily around your hand. Grasp the extended-length cork handle and cross steep terrain without fear of losing your grip on these poles or the mountain.
