Etna is a lightly padded heating vest with a built-in electric heating system powered by a power bank of your choice. Form-fitting, hip-length, stretch panels at the sides and side zip pockets at the front. Pressing the button with the Back on Track logo on the front of the west activates the electric heating system that immediately embraces the body with comfortable warmth. The settings allow you to select, or switch, between three heat levels; low (45°C), medium (50°C) or high (55°C). The vest is fully lined with Welltex®️ technology, which offers another advantage: the effect of reflected infrared energy – both from your own body heat and from the heat generated by the electric heating system. The perfect option in chilly weather or when you need to take a break and stay warm. The product is large in size, so that you can wear a thick sweater underneath. However, if you want to wear it over only a thin layer of clothing and close to your body, you should go down a size. NB! Power bank not included.
