When the mercury takes a nosedive, insulate yourself in the sure-thing warmth of this hearty sherpa jacket. The thick, deep 13.7-oz. performance pile delivers that essential extra layer of warmth on days so cold every inhale gives you brain freeze. Deep hand-warmer pockets, zippered chest and interior security pocket plus stretch binding at neck, cuffs and bottom for free-flexing mobility. Top off a tee in fall or layer it up over a sweatshirt when the deep freeze hits – and stay shiver-free all season long.
