Constructed with our own Dope Performance 15K fabric, which boasts a stellar 15k/15k waterproofing and breathability rating, and upgraded with a neoprene cuff and a cosy fleece lining for strength and warmth, along with a rugged polyurethane palm for abrasion and moisture resistance, the Ace mitts are designed to handle everything winter can throw at them. And for extra breathability, we ditched the plastic membrane, so say goodbye to sweaty hands! All this makes the Ace one card you definitely want to have up your sleeve for your next trip. Especially when you consider that they also have a non-slip palm print, too, perfect for slippery button lifts.
