The ScentBlocker Bone Collector ProTec XT Jacket is made from soft, quiet 100% polyester fleece fabric for premium warmth and comfort on cold-weather hunts. The outer surface of the fabric is treated with an anti-pill finish to ensure long-lasting wear. The WindBlocker laminate delivers premium windproof performance, while allowing moisture and perspiration to escape from the inside so you stay warm and comfortable. ScentBlocker's revolutionary Trinity scent control technology adsorbs up to 40% more human odors than activated carbon, keeping you fresher longer. BodyLock Technology strategically prevents easy escape of odor and forces it through the scent-adsorbing filter - at the wrists, neck, and waist - to allow maximum adsorption. The full-length front zipper and wind flap extend through the top of the high mock-neck collar for added protection against chilly air. Elastic binding at the waist and sleeve cuffs helps seal in body heat for even greater warmth. An innovative slit in the back allows for easy attachment and concealment of your safety harness. Two hand pockets and a vertical chest pocket - all with secure zipper closures - provide convenient storage for all your essential gear. System Layer 3. Imported.
