This vest is hands down a customer favorite, time and again. Equally comfortable layered under a shell or worn casually indoors, this bulk-free vest is made of a knitted, heathered polyester fleece dyed with a low-impact process that significantly reduces the use of dyestuffs, energy and water compared to conventional dyeing methods. Two zip pockets and one at the left breast. But apart from that, first and foremost, is: IT LOOKS GREAT ON! Lots of guys come in and can't decide which one to buy, and invariably come back for another color in a week or two. We have it in a women's version, too, so nobody will feel left out.
