Muddy Nucleus Heated Quarter Zip Features The Muddy Nucleus Heated Quarter Zip uses two heating elements positioned across the back of this next to skin base layer delivering radiant warmth powered by a single 10 000mAh battery. Three selectable heat settings low medium and high let the wearer dial in exactly the amount of warmth needed for the conditions on any given hunt. A power button conveniently located on the chest makes adjusting the heat level simple without needing to remove layers or stop moving. This heated base layer is designed to help hunters outlast lengthy sits in cold late season conditions. The low fitting quarter zip collar adds breathability while eliminating concerns about bunching when layering additional garments on top during cold weather hunts. Raglan seams are strategically placed throughout the garment allowing for a full range of motion whether climbing into a stand or settling in for a long sit. This combination of heated technology and thoughtful construction makes the Nucleus Heated Quarter Zip a practical addition to any late season layering system. Built by Muddy as part of their expanding lineup of heated hunting apparel this shirt is designed to keep hunters in the field longer.
