The Saskatoon cold weather soft shell vest features Heat Boost graphene sherpa - an advanced fabric made with graphene technology that provides superior light weight warmth. This hunting vest can be used as an outer piece into the later season or as a layering piece when the temps turn frigid. Graphene yarn knitted into the sherpa possesses the thermal conductivity, moisture wicking, and antimicrobial capabilities inherent to graphene. It harnesses your body's energy, absorbs the heat, and releases it back, surrounding you in a lasting radiant warmth. The Heat Boost graphene technology super-charges the sherpa's warmth with no increase in bulk, making this vest surprisingly light considering the warmth. Made in a stretch peached polyester bonded to a windproof film and Heat Boost graphene sherpa, this vest is critical piece to your laying system. The windproof film keeps out the chill, and a DWR finish sheds moisture and light snow. A high stand collar and drop tail hem provide additional protection against the cold. The Heat Boost graphene sherpa interior allows you to maintain core warmth regardless of the dropping temperature. With a multitude of pockets, you can easily keep all your gear handy. Use the harness access port when you're up in the stand. This vest is excellent for western stop and stalk hunts as well as blind and tree stand hunts. 1 Year Limited warranty
