AirDistance II™ is an innovative technological fabric. It’s 3-layered lamination, made of 3 parts: durable and self-gripping and polyamide layer, off-loading EVA foam and polyamide 3D spacer material. The external part is used to attach hard components. EVA foam off-loads these splints and the internal 3D spacer layer provides high air permeability and minimal water and moisture absorption. Waterproof material.
