When the mercury drops and the mountains call, Arc'teryx's warmest winter mitten answers with uncompromising protection for serious cold-weather pursuits. The Fission SV Mitten combines a dual insulation system featuring 200g PrimaLoft Silver and Coreloft Compact Gold Eco to deliver exceptional warmth that performs even when wet, while the robust 275g Burly double weave softshell construction provides wind protection and abrasion resistance for technical winter activities. Despite its maximum warmth credentials, the articulated patterning maintains the dexterity you need for ice climbing, backcountry skiing, or winter mountaineering, while the extended gauntlet design seals out snow and cold around your wrists. With a durable goat leather palm that grips confidently in the harshest conditions, these technical winter mittens prove that you don't have to sacrifice performance for warmth when the stakes are high.
