Warmth on the go. The Etna W's Vest provides instant warmth without the need for bulky clothing or multiple layers. A press of the logo button on the front of the garment activates an electric heating system that wraps the upper body in a warm layer.The Etna Heated Vest is an ideal companion outdoors - or when you want to take a break and keep warm between training sessions. The body-hugging fit and light weight ensure maximum comfort and freedom of movement.The sporty waistcoat is lightly padded and has an integrated electric heating system that is powered by a portable powerbank of choice. The settings allow you to choose between three heat levels: low (45° C.), medium (50° C.) or high (55° C.).The waistcoat is lined with Welltex®fabric, which offers an additional advantage: the effect of reflected infrared energy, which in this case is derived from both body heat and heat generated by the electric heating system.
