Härkila HEAT Control® heated underpants

Hrkila HEAT Control Thermal Underpants
The Heat underpants, made of 80% nylon/20% elastane, from Hrkila are the perfect mid-layer on cold days. They are equipped with the innovative HEAT Control technology, which ensures optimal temperature and thus extends the period during which you do not freeze even in the coldest temperatures. With the HEAT technology, heat is effectively distributed through a thin heating membrane. In addition, the long underpants feature two heating elements and a heat-reflective lining. Temperature regulation is done via the HEAT button on the chest. The HEAT button allows switching between three preset temperatures. Once the desired temperature is reached, the HEAT technology switches to standby mode to extend battery life. If the temperature falls below the set value, the heating membranes turn back on. You can use all types of power banks with a USB connection. The underpants can easily be worn as a base layer for sports, such as hiking, skiing, or mountaineering.
