Can be placed under ski gloves, motorcycle gloves, work gloves, etc. Therm-ic Thin Ultra Heat heated inner glove can be worn under any other pair of standard gloves (ski gloves, motorcycle or snowmobile gloves, outdoor gloves, work gloves, etc.). Knitting technology combined with recycled polyester provides effective insulation and breathability in cold weather, heated and flexible S.E.T. line distributes heat evenly around all fingers and lasts up to 7 and a half hours.
