Sitka's Waterfowl apparel was designed with the waterfowl hunter in mind, setting up decoys and settling into a blind can be a very psychical process causing you to sweat even in frigid conditions—to combat that, Sitka gear is designed to be layered allowing you to shed layers during peak activity and to add layers while waiting for the birds to come into range. Waterfowl hunting is done in a high contrast environment. Skylight from the horizon or light reflected from the water will shine through gaps. Sitka's Waterfowl Marsh pattern is high in contrast to be consistent with the environment. The GORE™ OPTIFADE™ Waterfowl Marsh concealment pattern is designed to make a hunter almost invisible to incoming waterfowl in whether it be in a marsh or crop field before and after harvest.
