Atlas - BC24 Snowshoe (Canyon) - Men's: Spring-Loaded Suspension (SLS) allows for natural articulation of the foot for unmatched control and comfort. Summit binding consists of waterproof urethane straps that stay dry and light and collapse flat for easy packing. ReactiV 7075 aluminum frame is Atlas' stiffest chassis for an extremely responsive-feeling suspension, with the 7075 aluminum being the lightest strongest tubing available. Holey-1 toe crampon has a 3D-formed design that allows for lighter weight and structural strength. Parallel traction rails under the sides of your feet where you get the most control provide increased traction while traversing. Heel lift bar relieves calf muscle fatigue while ascending steep slopes (bar stores flat when disengaged). Duratek decking is durable and lightweight. Surface area: 173 sq in. Weight (per pair): 4.13 lbs (1.87 kg). Load: 100 to 200 lbs.
