Härkila Heat USB-C Long johns Men Willow Green/Black M

Long underwear with integrated heating system for individually adjustable warmth on cold days. The elastic fit, intelligent temperature control, and robust construction make it ideal for hunting and outdoor activities.
The Härkila Heat Long Underwear was designed for hunters and outdoor enthusiasts who want to adjust their warmth to the respective conditions. Integrated heating zones in the lower back area and over the knees can be conveniently set to 35, 43, or 50 °C via the button in the waistband. The flexible heating technology moves with the garment, can be folded together, and is fully machine washable.
The close-fitting cut with high stretch content ensures excellent wearing comfort and unrestricted freedom of movement. A power bank of your choice (not included) can be connected via the waterproof USB port and, for example, stored in the pants pocket. With a 10,000-mAh power bank, the heating system provides up to about 7 hours of warmth at an outside temperature of 0 °C on the highest setting. The intelligent temperature control automatically switches off the heating elements as soon as the desired temperature is reached and activates them again when the temperature drops. This ensures efficient energy use and consistent thermal comfort. A waterproof stuff sack is included.
