A size large Rapha bib is like a medium in other brands. Worn on their own these very snuggly ones made from ThermoRoubaix fabric are superbly comfy on long steady, rides. For mountain bike use, they’re probably overkill to wear under baggies on shorter blasts.
The material is tough and a high back panel works well with meshed straps to keep you toasty without sweat build-up. There’s a key pocket in the lower back and the Cytech pad is one of the most comfortable we’ve tried. Flatlocked stitching is used throughout and there’s a Rapha logo’d white stripe below the knee.
