Warmth without bulk. Made with Heat Boost graphene technology, these Matterhorn waterproof bibs provide all-day warmth of a heavily insulated garment without the heft. Designed for late season bone-chilling cold weather hunts when staying warm is critical, these bibs are made in a heavily brushed tricot in Tarnen or Disruption camo bonded to a windproof film membrane. They are fully lined with Heat Boost graphene sherpa - a graphene enhanced fabric engineered for superior warmth. Knitting graphene yarn into the sherpa imparts the thermal conductivity, moisture wicking, and antimicrobial properties inherent to graphene. The graphene harnesses your body's energy, absorbs the heat and releases it back, surrounding you in radiant warmth, even on extremely cold days. The 100% waterproof taped seams and storm flaps keep you dry, and a multitude of pockets provide plenty of storage. The zipper on the bib front is two-way making it easy to access your pants without fully unzipping. The 2-way leg side zippers extend to your hip, making it simple to pull on and take of the bibs without removing your boots. A hidden crotch gusset and articulated knees make it easy to walk, climb, bend, and sit when wearing these heavyweight bibs. A waterproof, abrasion resistant patch in the seat area provides extra protection when sitting in wet, cold weather conditions. These are the ultimate in cold weather hunting bibs.1 Year Limited Warranty
