A push button on the HEAT products allows you to switch between the three pre-set temperatures with a simple press. The button also contains our HEAT Control technology, which lets you connect the product to your mobile phone via Bluetooth.
*The HEAT Control app. With the HEAT Control app, you get maximum control over your Härkila HEAT products. With its intuitive design, you can choose the perfect temperature by rotating a dial in the app. Be aware that the HEAT Control app can be used only with the HEAT jacket and vests, not with the HEAT baselayer. The temperature of the HEAT baselayer can easily be set with the push button on the garments.
