We have specific kits for certain days, and the PEARL iZUMi Pro Air Bib Short is our top choice for all-day grinds. It uses the stretch weave Pro Transfer fabric for superior compression and support and features a laser-cut bib-strap design for next-to-skin comfort. Pearl Izumi's PRO Levitate chamois provides comfortable support for when we're halfway through a 70-mile day, and BioViz reflective elements keep us seen when the sun sets before we make it home.
