The exclusive ISOTREK fabric membrane is a hydrophilic polyurethane film with exceptional characteristics. The membrane is continuous, without perforations, and the evacuation of the transpiration is produced by a chemical exchange: the hydrophilic molecules of the polyurethane "manage" the water vapor that is evacuated to the outside thanks to the difference of pressure between the inside - warmer - and the outside. The most evolved membrane for aerobic use.
