The FIRSTGEAR Heated Socks in Medium use micro-fleece and flat heat technology to provide low-profile warmth that fits under boots or another sock layer. They plug into a Heat-Troller through heated pants or run independently with the optional extended Y cable. Comfortably thin stretch fabric wicks moisture while coaxial plugs offer reliable connectivity; each sock delivers 9 watts (.7 A at 13.8 V) with heat elements across the toes. Extended Y cable sold separately; one-year warranty included.
