Whether you're going for a casual pedal around the park or down the boardwalk, or even heading into spin class, the Sugoi Sprint Shorts are the lightweight, casual-looking shorts for the job. The RC 100 Women's chamois is ultralightweight for comfort on and off the bike, and uses Invisa chamois construction to eliminate the stitching and create a more flattering silhouette. Helix fabric provides support with stretch that moves with you while allowing air to flow for comfort throughout aerobic activity.
