The battery life is the average of 100 random samples. The minimum value may vary by up to 10% in individual cases which does not entitle the customer to make a complaint. The temperature is measured directly at the heating elements and is slightly lower on the outside of the fabric due to the windchill effect.

New since September 2018 are our Thermo Ski Gloves, which are lined and insulated in addition to the integrated heating element. This means that these gloves can be ideally used as outer gloves for skiing and all other outdoor activities. A very modern resistant material on the palm of the glove allows a very good grip.
