Muddy Nucleus Heated Quarter-Zip Features The Muddy Nucleus Heated Quarter-Zip is part of Muddy s all-new assortment of hunting apparel and accessories built specifically to help wearers outlast lengthy sits in cold conditions. Two heating elements positioned across the back of this next-to-skin base layer radiate warmth generated by a single 10 000mAh battery giving hunters an active source of heat rather than relying solely on passive insulation. Three selectable heat settings low medium and high let wearers dial in exactly the amount of warmth each hunt demands. Adjusting between settings is as simple as pressing the power button conveniently located on the chest so no fumbling with hidden controls is required. The low-fitting quarter-zip collar improves breathability and eliminates the bunching that can occur when layering this shirt underneath additional cold-weather gear. Raglan seams are strategically placed throughout the garment allowing a full range of motion whether reaching for a bow raising a rifle or climbing into a stand. These design choices reflect Muddy s focus on building apparel that performs actively in the field rather than simply sitting as a passive layer. This Brown Clay colorway sized 3XL is ready for sale at GrabAGun for hunters who want adjustable battery-powered warmth through the coldest late-season sits.
