Innovative merino outerwear delivering total concealment, superior warmth and comfort. The RiverWolf™ Systems Jacket is groundbreaking first-of-its-kind merino outerwear designed specifically for whitetail treestand hunters who demand peak performance in the harshest conditions. Constructed with our jacquard knitted Merino Fleece Tec Shell and Merino FlexTec paneling, this jacket delivers exceptional durability, flexibility, and silent movement. 100gsm of paneled QuietLoft™ insulation provides superior warmth without unnecessary bulk, while Windseal-TC3™ technology ensures complete windproof protection to keep you comfortable during long, exposed sits. A tricot lining infused with our proprietary ScentTech lining completely destroys odor and also controls perspiration, enhancing comfort over extended hunts. Thoughtful features like a 3-piece visored hood with adjustability, zippered side pockets with internal cuffs, upper chest pockets, and a harness vent at the upper back provide both function and safety. Articulated sleeves and exclusive Fleece-Flex™ cuffs offer a quiet, natural fit, while a lower drawstring hem seals out the elements. Designed for hunters who won't compromise on silence, warmth, or performance, the RiverWolf™ Systems Jacket is the ultimate outer layer for serious whitetail hunters. Regular Sizes: M-3XL. Tall Sizes: LT-2XLT. This garment is a standard "bowhunter" fit and built to be conservative and keep excess fabric and bulk out of the way. Articulation through paneling and sculpting on our garment design moves with your activity while keeping garment profiles discrete with less bulk. We suggest ordering true to size as the fit still accommodates for mild layering underneath.
