Sealskinz have engineered a fabric technology that is designed for road cyclists that seek maximum waterproof performance from their cycling clothing. The Sealskinz waterproof leg warmers totally waterproof, windproof, breathable and designed for the wettest conditions when you have to get out & put in the training miles! The triple layer, lightweight waterproof stretch fabric fits close to the skin for total comfort. With a hydrostatic head of 10, 000mm, water simply beads & rolls off the outer face of the fabric meaning you stay drier for longer.
