Windproof underwear – GORE-TEX WINDSTOPPER windproof short sleeve undershirt for outings on cooler days. Stretch WINDSTOPPER panels protect sensitive areas keeping you warm but wicking away moisture. – BASE LAYER – The first layer. This undershirt is part of the BASE LAYER series, designed as the first layer of the GORE BIKE WEAR outfit system. The combination of polypropylene and WINDSTOPPER fabrics provides exceptional year-round comfort. These products are divided into three categories: ‘cold’, ‘cool’ and ‘all year’, and offer optimal comfort in a range of external conditions. – WINDSTOPPER heat effect – Due to the special WINDSTOPPER membrane, the effects of wind are completely blocked so the body stays warm longer. Ordinary fabrics don’t block the wind allowing the body temperature to drop (the ‘wind chill’ effect) cooling muscles and lowering performance. – Care Instructions – Easy care, washable at 40° C, tumble dry on low, do not iron, color-sort and wash separately for first wash. – GORE BIKE WEAR – Bob Gore, the current Chairman and son of the founders, invented the revolutionary GORE-TEX membrane in 1969. The membrane is characterized by the unique features that make it waterproof, windproof and breathable. For more than 30 years the company has designed products specifically for the needs of the modern cyclist. Innovative GORE-TEX and WINDSTOPPER technologies ensure maximum comfort and protection in all weather conditions. – Internal research laboratories are constantly striving to offer sustainable products without compromising on quality or function. All products and brand materials from GORE BIKE WEAR meet the requirements for Oeko-Tex Standard 100.
