When conditions run from whistling gusts and drifting powder to melted slop, relying on the baseline of warmth protection provided by the Girls' Capilene Crew is a steady comfort. Easy-wearing polyester/spandex sueded jersey fabric is treated with a wicking finish and Polygiene permanent odor control, for superior warmth, moisture- and odor-management. Self-fabric binding at collar with inside neck tape is soft next-to-skin; offset shoulder seams and flatlocked seams throughout eliminate chafing. Elastic thumb loops provide secure hand coverage. Slim fit for layering under midlayers and outerwear. Fair Trade Certified ¾ sewing.
