Gerbing’s trouser liner is made of viscose and can be worn under tight fitting trousers. It is as thin as a medium sweater. The heating pads are insulated with Meida™ insulation. The liner heats on the front of the legs and the hips. Gerbing has sown in a 50cm zipper to allow the trouser liner to easily be fitted while wearing riding boots. Each liner draws about 44 Watts/ 3.5 Amp., and is constructed with the same unique high-density heating pads used in our jackets and other garments. The trousers are equipped with connection plugs for easy connection to Gerbing's heated socks.
