When Arc'teryx launched their glove and mitten line, they did it with a goal to be the best. Their Fission Mittens completely live up to that goal. The GORE-TEX XCR waterproofing offers 100% protection from wind and water while still allowing internal moisture (sweat) to evaporate out. The PrimaLoft insulation is super lightweight and incredibly warm and doesn't produce the bulk that comes with down. The articulated shape is contoured to ensure the perfect fit of a natural hand so their comfortable and move without bunching. The Arc'teryx Fission Mittens are top of the line gloves for the coldest, most extreme environments. They'll change the way you think about winter.
