Late-season whitetail hunters require layering systems that work a little harder, offering up more than warmth to outlast all-day sits through winter's worst weather. They need complementary layers that seal out wind, cold and moisture while simultaneously trapping their body's heat and warming them from the inside out. And, because long, cold sits quickly deplete their body warmth, they need gear ready and willing to do some of the work for them. Part of Muddy's all-new assortment of hunting apparel and accessories, every item with the Nucleus name delivers a long-lasting and adjustable heat source that sees passionate tree stand hunters through their longest, coldest days in the field. A staple in this new lineup, the 3.7-volt, 3,500mAh Nucleus Power Bank keeps all your heated gloves and socks charged up on the go and operational during all-day sitswhether you need a back-up power supply in the stand, or to charge up quickly when you're in camp or road-tripping between hunts out of state. This compact, rechargeable power bank includes one USB-C charging cable and comes as a set of two, meaning you'll make even faster work of getting heated gear up and running when you need it most.
