Here’s a big, warm hug. 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 Kanetsu AirVantage solves this comfort vs. function dilemma by being adjustable, i.e. by using more or less air in the insert, the overall closeness and consequent warming efficiency of the garment can be adjusted. Also, because air is an effective insulator, the passive warmth of the vest is greatly improved, as the air alone extends the temperature range that doesn't require using power for heat.

A Terrific/Huge/Quantum advance in heated garment technology. No kidding...
