This hooded half-zip fleece shirt is good for duck hunting or just living the Rocky waterfowl hunter lifestyle. The upper body and sleeves of this men's camouflage shirt are made of waterproof and wind-resistant Taslon nylon in Mossy Oak Shadow Grass BladesTM camo. Taslon is a woven polyester fabric designed for durability and strength. It is stain-resistant and dries quickly. It also wicks moisture from your body so you're warm, but aren't sweating while on the hunt.
