Motorcycle riders who enjoy spending their days in the saddle understand the value and versatility of layering. Each layer of clothing traps insulating air molecules, so some thinner layers such as the Zerofit HeatRub base layer usually keep you warmer than a bulky layer. And as the temperature changes during the day, layers can be added or removed as needed.

The Zerofit The unique heatsink product line called HeatRub comes in two versions: Ultimate and Move. Inside the HeatRub Ultimate foundation are extra-long fibers that gently rub against the skin to generate frictional heat, which is trapped in the small spaces around the fibers. The fibers are very soft, similar to cashmere or alpaca.

The HeatRub Ultimate base, available in long sleeves and leggings, is made of a four-way stretch fabric that blends acrylic (69%), nylon (21%), wool (7%), polyester (2%), and polyurethane (2%). According to Zerofit, the HeatRub Ultimate backing has a CLO rating – a measure of a garment’s ability to insulate – of 0.74. A thick sweater has a CLO of 0.35, so the Ultimate backing is said to be twice as warm as the sweater and five times warmer than the standard backing.
