The Helix Collection has paved the way for the most technically advanced, competition level cycling apparel on the market. The advanced lightweight, aerodynamic fabrics and Pro Tour Fit work together to regulate your core body temperature and keep you riding at your peak in the most extreme conditions. Vortex Panels and Z92 Compression sleeves reduce air resistance while the SLR Ion Fabric body and mesh side panels contour along the natural body lines to provide a superior fit and excellent moisture management. Now featuring laser cut cuffs which create a smooth, seamless transition from skin to jersey. This reduces air surface tension and locks the cuff into position. No slippage or movement means laser sharp tan lines!
