The Coldfront Down Mitts blend bluesign approved and recycled materials with responsibly sourced down insulation into a down mitt for extreme cold weather warmth. A 100% recycled polyester 20D ripstop outer is stuffed with compressible RDS-approved 650 down for the coldest days, and a silicone print on the palm and thumb provides added grip and durability. The Coldfront Down Mitts are designed to stuff deep inside a pack when not needed. When the thermometer drops into the single digits, pull it out and loft it up in seconds for supreme warmth.
