Sealskinz have engineered a fabric technology that is designed for road cyclists that seek maximum waterproof performance from their cycling clothing. The Sealskinz waterproof cycling tights are totally waterproof, windproof, breathable and lightweight designed to be worn over bib shorts for use in the wettest conditions when you have to get out & put in the training miles! The triple layer, lightweight waterproof stretch fabric below the waistline 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. Lightweight & compact, the waterproof cycling tights can be rolled up & stored in a jersey pocket for use when it starts to rain without having to remove bibshorts. Poly lycra fabric on waist & features & elasticated drawstring on waistband for a comfortable fit.
