Perhaps the most important layer in any late-season whitetail hunter's arsenal is a heated base layer that traps warmth and quickly generates more when your mind, body and spirit need it most. Designed to serve as the core of your late-season layering system, the Nucleus Heated Bottoms keep die-hard whitetail hunters warm through the worst conditions late season can dish out. Choose from low, medium, or high modes to activate the two heating elements on each thigh, each powered by an included 10,000mAh battery. The current setting can be altered using the silent, push-button power control below the waistband. Easy to layer, these bottoms are held in place when adding or removing additional articles of clothing thanks to integrated stirrup loops at the bottom of the pants. Pair their superb layer-ability with the anti-static and anti-pilling features of the fabric and you've got a key tree stand-hunting layering component that will withstand the longest, coldest hunts for many seasons yet to come.
