The ScentBlocker Bone Collector ProTec XT Pant 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 waist and leg cuffs - to allow maximum adsorption. The adjustable waist, belt loops, and zippered fly with double rubber snap closure ensure a custom, personalized fit. Two jeans-style inset pockets, two bellowed cargo pockets with side-entry zippers, and two snap-closed rear pockets provide ample storage space for all your essential gear. Elastic ankle cuffs help seal in body heat for even greater warmth. The 20" leg zippers allow for easy on and off over boots or shoes. System Layer 3. Imported.
