Arc'teryx Women's Delta AR Zip Shirt

Featuring an incredible warmth to weight ratio, the Arc'teryx Women's Delta AR Zip is a perfect companion for cold days in the mountains. It packs down small and weighs just 9.6 ounces in size medium yet it's an unbeatable insulating layer whether worn under a shell or on its own. The trim fit provides superior wicking performance, a real plus when physical effort negates chilly temperatures. A deep cut zip provides further comfort control and the longer length keeps rain and snow from creeping inside.
