The heat have 4 different temperature levels. This way you can choose your own ideal temperature, depending on whether you get cold hands quickly or not.If you are no longer cold, you can turn the heat off without having to take off the „Heater“ or the outside gloves, because the on/off button is located on the outside of the „Heater“. The „Heater“ is equipped with high-tech carbon fibres that conduct the heat. These fibres are not only extremely thin and flexible, they also ensure an even distribution of heat. The heating time is between 2 and 6 hours, depending on the temperature level, but that does not mean that you have to have cold hands after that. Simply replace the accumulator, without even having to take off the gloves.
