The FIRSTGEAR Heated Socks in XL use micro-fleece and flat heat technology to warm feet without adding bulk, letting you layer under boots or regular socks. They can plug into a Heat-Troller through heated pants or be powered alone with the optional extended Y cable for standalone use. These thin, form-fitting socks wick moisture, use coaxial plugs for reliable connections and deliver 9 watts per sock (.7 A at 13.8 V) with heating elements that cover the toes; extended Y cable sold separately and a one-year warranty is included.
