This thermal underwear has heating zones woven into the fabric: 12 in the top, 10 in the long johns, 22 in the full set. It is powered by USB from a power bank that sits in a pocket (power bank not included), so you choose how long it runs. Three settings cover about 77 to 131 °F (25 to 55 °C), and the extra-thick fleece lining keeps the warmth close even when the heat is off. Pick the men's or women's cut in black or gray, as a set, top only or pants only.
Perfect for: ice fishing, winter commutes, outdoor work, skiing and cold stadium seats.
