Firstgear's no one left behind policy ensures that riders of any model motorcycle can take advantage of the warming effects of heated apparel by choosing between either the 65- or 90-watt versions. Good for low-amperage bikes or passengers not requiring as much heat as the rider, the 65-watt units minimizes the draw on the bike's charging system. Efficient warming is dependent upon close proximity to the body. Firstgear reduced the amount of sizes while ensuring a good fit by incorporating stretch panels into the liner's design. The long-sleeve liner cocoons its wearer in warmth by incorporating heating elements across the upper and lower back, down the sleeves, around the neck and, to combat the effects of windchill, the liner concentrates heat in the front of the jacket.3 Make sure to check out our Firstgear Heated Gear Buyers Guide
