These lightweight and packable MSR Lightning Snowshoe Tails add flotation when you are carrying a heavy pack, or for deep-snow days. Bringing the advantage of adaptable flotation to the ultralight 360 TractionTM frames, the tails are light enough to bring on any trip, allowing you to take advantage of the agility of a smaller, primary snowshoe in packed conditions, while adding 5 inches (13 cm.) of flotation on-demand for deeper snow, or when carrying heavier packs.
