📍GUC📍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 60 g provide heat at three different levels for up to 10 hours. They are concealed in the extra long AVIATOR.GTX cuff and you can hardly feel them. The gloves' heating system is easy to operate with a single button on each glove. Zanier Heated Gloves Include: • 2 sets of Rechargeable Batteries • Charging Cord • The flame shaped LED 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. Straps and Velcro fasteners were deliberately not used making them ideal for flying at extreme heights. The PrimaLoft insulation incorporated into the AVIATOR.GTX, the GORE-TEX membrane and the moisture-regulating BREATH lining also protect against the rain and wind. Including Leash and TOUCH function 💥Slight flaw in 1 glove, does not affect use💥
