The GORE BIKE WEAR ULTRA bike pants seal out the weather, breathe well and have an ergonomic cut specific to the cyclist posture. Made with Gore-Tex(R) PacLite(R), which is specifically engineered to be light, packable and more breathable than other 2- or 3-layer Gore-Tex fabrics. The lightest, most packable fabric from Gore-Tex, PacLite uses a durable unlined membrane to keep you dry in the wettest conditions. Factory seam-sealed; earns Gore's ''Guaranteed to Keep You Dry'' rating. Adjustable elasticized waist with drawcord personalizes fit; high waistline offers full coverage while in riding position. Articulated knees and an adjustable leg width improves aerodynamic fit in bike posture. Zippered back pocket securely holds essentials; pants pack into pocket and attach to your bike frame. Reinforced seat resists the wear of the saddle. Reflective logo and piping along side seams increase visibility in low light.
