The RaidLight StretchLight MP+ Mitten is a ultralight waterproof shell to keep your hands dry. Originally designed to meet the required gear specification for UTMB they have become a staple in many people's trail running kits.
At only 20 grams (0.7oz!) they pack down small enough to be carried anywhere and to add that extra layer of protection when needed. The seam taped StretchLight MP+ fabric allows for a comfortable fit while keeping you dry.
