Forget the meaning of the word ‘cold' when you wear the Primaloft insulated Spyder Men's Hallet Jacket. Whether you layer the Hallet Jacket under a shell, or just wear it alone on the mountain or in town, the beefy insulation keeps you comfy in cold weather. The asymmetrical zipper layers without adding bulk for a warm, but non-constricted, or weighed down feel. This Spyder insulated jacket's micro-fiber chin liner eliminatesd chaffing when you have the collar zipped up. And the key clasp inside the hand warmer pocket gives you quick access to your keys at the end of the ski day.
