The ZANIER Heat Technology is based on highly developed textile heat elements and a unique electronic control system. The robust lithium ion batteries which weigh just 60g provide heat at three different levels for up to ten hours. They are concealed in the HOT.STX cuff and you can hardly feel them. The gloves’ heating system is easy to operate with a single switch on the white battery. The flame shaped light shows the chosen heating level (yellow, orange, red) and shines through the transparent upper material. The supplied USB charger unit recharges the batteries overnight. The gloves’ heating system is robust and even withstands hard knocks. The model can also be used without heating and offers a TOUCH function on index finger and thumb. The incorporated ecological Sympatex® membrane functions as effective protection against the cold and rain and offers optimum breathability. ALU ARMOR, an aluminium layer on the membrane, also provides perfect thermal insulation in the glove. High-quality materials such as the finest goatskin and 4-way stretch also contribute to maximum comfort. Thanks to the incorporated inner glove, the HOT.STX mittens promise exceptional freedom of movement. Zanier - Hot.STX Mittens black
