Experience warmth at will and on the go. “Etna” W’s Vest provides instant warmth at your convenience, without the need for bulky clothes or several layers. At a push of the logo button at the front of the garment, an electrical heating system activates to wrap your upper body in a warm embrace. The “Etna” Heated Vest is an ideal companion in the outdoors – or when you need to take a break and keep warm between training sessions. Close-to-body fit and low weight allows for maximum comfort and freedom of movement. This slender vest is slightly padded and features an incorporated electrical heating system, powered by a portable power bank of your choice. The settings allow you to choose between three levels of heat: low (45° C.), medium (50° C.), or high (55° C.). The vest is lined with our Welltex®️ fabric, giving it an additional advantage: the effect of reflected infrared energy; in this case, harnessed from both body heat and the heat produced by the electrical heating system.
