MSR Evo Snowshoe Tails/Extenders | Fits MSR Evo SnowshoesModular tails add 6 in. (15 cm) to any Evo snowshoes for increased flotation. Our Lightning Modular Flotation Tails bring the advantage of our proprietary, adaptable flotation to our ultralight 360 Traction frames. Small and light enough to bring on any trip, you can take advantage of the agility of a smaller, primary snowshoe in packed conditions, while adding 5 inches (13cm) of flotation on demand for deeper snow, or when carrying heavier packs.
