The Elastic Interface® Road Performance Carbonium chamois we’ve selected for these premium SKINS C400 men’s compression bib shorts has been specially engineered to meet the expectations of pro cyclists who need all the support they can get to gain ground over long hours in the saddle. Ultra high density perineal inserts have been engineered & tailored according to university research & placed in key pressure points for optimum performance in the road bike position. The perforated base layer provides maximum ventilation & is quick drying. SKINS C400 is the only high performance range to use in-motion measurement to define the correct level of compression needed during activity – we call this Dynamic Gradient Compression. This helps improve circulation, getting more oxygen-rich blood to your muscles & re-circulating blood lactate so you can perform better & recover faster. In addition SKINmuscle+ Muscle wrapping supports key cycling muscle groups helping to reduce post-exercise muscle soreness. Other features of the C400 bib shorts include: A highly breathable engineered soft mesh bib. Ultrasonically cut & bonded inseams & PU bonded hems for comfort & a smooth finish. 360° reflective detailing for high visibility at night. 50+UV protection in non-mesh areas. These bib shorts also protect your modesty with opaque, anti-pill front & back panels. Wear with a C400 compression jersey to give your body the ultimate circulatory benefits of SKINS.
