Endura's flagship Pro SL Bib Shorts are more comfortable than ever thanks to new multi-fabric construction that offers support where you need it most, yet ensures your movements on the bike are unrestricted. The unique lumbar support panel made from high-powered Italian Lycra wraps around your lower and back sides, holding the bib short firmly in place while taking pressure off the straps. This gives the shorts a barely-there feel that's greatly appreciated on longer rides.
