MSR Women's Lightning Ascent Snowshoe (2017 Model) Unrivaled Traction: 360 Traction frames deliver edge-to-edge grip, and split teeth of Torsion2 crampons better distribute forces for more continuous contactdelivering unmatched traction on any terrain, in any conditions. Secure Attachment: Two-piece, independently conforming PosiLock AT bindings create our most secure, freeze-resistant attachment, regardless of footwear. All-Condition Adaptability: Add-on Modular Flotation tails (sold seperately) allow you the maneuverability of a smaller, primary snowshoe with the added, on-demand flotation of optional, 5-inch (13-cm) tails. Uphill Efficiency: Ergo Televators reduce fatigue and increase traction on the steeps with an ergonomic design that engages with a flick of a pole grip. Low-Profile: Narrow frames are ideal for women, those with a narrow gait, or anyone seeking the lightest snowshoe possible. Made in the USA and Ireland
