Sealskinz have engineered a fabric technology that is designed for road cyclists that seek maximum waterproof performance from their cycling clothing. The Sealskinz waterproof bib tights are totally waterproof, windproof, breathable & lightweight designed for 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. The upper rear bib section is made from a soft, lightweight & stretchable lycra mesh for comfort and ventilation. The front bib & lower back is made from a polylycra fabric which provides close fitting comfort & added warmth. The fabrics are bonded together with flat lock seams which provide durability & comfort. The thermo moulded Liege HP chamois from Cytek is guaranteed for superior comfort and protection providing all day riding comfort. Constructed with a combination of 3 different foam densities which cover the Perineal & Ischiatic main pressure point areas ideal for longer rides lasting up to 7 hours. The Coolcube fabric construction on the top of the pad is engineered to be soft, breathable & quick drying.
