One of the challenges to the efficiency of electric vests is the problem of conducting the heat from the elements to the rider. Traditionally, this has meant a closely-tailored (and often uncomfortably restrictive) garment for maximum heat transfer. The AIRVANTAGE® insert solves this comfort vs. function dilemma. By blowing more or less air into the internal bladder, the overall closeness and consequent warming efficiency of the garment can be adjusted. Also, because air is an effective insulator, the warmth of the vest is greatly improved, and the air alone extends the temperature range that doesn’t require using power for heat. An advance in heated garment technology. Neat. Includes fused power cord and lighted switch. Black Gore-Tex® Windstopper® shell with a durable nylon lining. Patent Pending.
