The Sugoi RS Pro Short uses three strategically placed fabrics for maximum comfort on the road. The outer legs utilize Sugoi's Ultra Aero fabric that's dimpled for a slippery aerodynamic surface. Slimmed down front panels leverage ultra thin Tri Force fabric for enhanced breathability and temperature regulation. Adding durability along the inner legs, the short's Firo fabric reinforces the chamois area for extra resistance against saddle abrasion. Designed to eliminate chafing and bulk, the included Formula FX Chamois is molded and welded for an excellent fit without an inseam meaning there's no seam rubbing against the saddle. This chamois features breathable perforations and a V notch for extra ventilation on hot summer rides. Its 4 way stretch fabric and advanced lamination provide a smooth, seam free surface that conforms to your body, while the welded center channel and high density vibration dampening relieve pressure and fatigue from long, grueling rides. Moreover, you'll find the short's clean finish leg grippers prevent the short riding up, and its single side pocket holds your favorite media player or energy gels for added convenience.
