The Huntworth Vostok Heat Boost Trapper Hat in Vertek hybrid camo utilizes Heat Boost graphene and a waterproof/windproof film to keep the cold air out and the warm air in. Graphene-infused yarn traps body heat and radiates it back onto your body, effectively making you warmer with less bulk. The graphene yarn knitted into the hat possesses the thermal capacity, moisture-wicking, and scent reducing capabilities inherent to graphene. A thick faux fur lining wraps around the sides of your head and extends through the ear flaps for extra warmth. The earflaps can snap down for more insulating coverage or flipped up for better hearing. A grommet hole over the ears aides in sound audibility. An adjustable strap has a quick-release buckle for easy on/off. A classic hunting hat made for the worst weather, trust the Vostok trapper hat in Vertek for all your late season hunts.
