The Craft Glow Bib Short was designed for long distance cycling, especially in hot weather. The Glow incorporates several innovative technologies to protect your muscles and increase your stamina in cycling's most demanding conditions.The main body fabric is a durable Lycra with excellent elasticity. Not only does the Glow reduce fatigue by holding the muscles in place to protect from the road's relentless vibration, it provides support while you're asking your muscles to push harder and harder mile after mile. The uppers are made with a highly breathable hexachannel polyester fabric. As this fabric promotes airflow, it works with your body to regulate temperatures and increase endurance. Craft also treated the bib short with Coldblack, which reflects the sun's heat to maintain a cool surface temperature and protect your skin from harmful UV rays. The bib shorts are form fit and were designed with the moving body in mind. To this end, the panels have been cut to follow the anatomy of the body while in the cycling position. All of the seams have been flatlock stitched to minimize chafing, and the wide leg hems are silicone printed to keep the bibs in place without the irritation of thin elastic.The bib shorts feature Craft's Performance chamois to keep you riding in comfort hour after hour. This multi density chamois was sewn from three different densities of cushioning strategically placed to relieve pressure and eliminate numbness. Not only does it provide support for your sit bones and cushioning for your soft tissue, it is also antimicrobial and moisture wicking to keep you cool and dry.
