The Black Diamond Mercury Mitt is a popular choice for year-round use and combines a BD.dry™ waterproof insert with an Empel DWR on the shell. The removable insulated liner, filled with Primaloft Gold Cross Core, dries quickly, and insulates even when wet. A four-way stretch fabric shell and a long gauntlet cuff keep spindrift and moisture outside, while the goat leather palm and additional reinforcement layer stands up to rocky terrain, repeated rope handling and the general wear and tear associated with dedicated mountain use.Black Diamond Womens Mercury Mitts Features: Built with BD.dry™–our engineered waterproof/breathable/windproof solution Featuring GTT Empel™ Technology—a revolutionary water free and PFAS-free DWR that’s superior in performance and substantially more durable than other DWR solutions 100% waterproof BD.dry™ insert Durable but lightweight, 100% recycled shell fabrics with stretch for the freedom to move Goat leather palm with reinforcement patch Size Range: XS - L Temperature Range: -26/-18 C (-15/0 F) Insulation: [Removable Liner Backhand] 340 g PrimaLoft Gold w/ Cross Core Weight per Pair: 243 g Country of Origin: Vietnam
