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 has been 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 adjusted via the button in the waistband to 35, 43, or 50 °C. The flexible heating technology moves with the garment, can be folded, and is fully machine washable.
The body-hugging fit with a high stretch content ensures excellent wearing comfort and unrestricted freedom of movement. The waterproof USB port allows you to connect a power bank of your choice (not included) and store it, for example, in your pocket. With a 10,000-mAh power bank, the heating system provides up to about 7 hours of warmth at the highest setting at an outside temperature of 0 °C. 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.
