While the moisture managing properties of Capo's SL Bib Shorts have been a staple since the advent of Lycra kit in the '70s, the latest trend of gentle, fatigue fighting compression is a newer feature that not every manufacturer has begun to incorporate. Capo has, and the SL Bib Shorts combine eight panels of medium gauge Lycra for a body mapping fit that helps to stabilize muscles and reduce the imperceptible oscillations that contribute to fatigue over a day in the saddle. Ideally, this keeps legs fresher, longer, helping to ensure the engine has a little left in the tank as the race or ride winds up. The material's confident hold also feels pretty damn good, and the Lycra extends that support relatively far up the torso, maintaining compression across the lower stomach and back with the usual mesh only taking over for the chest and shoulders. The bibs help keep the D4 EIT chamois in place, ensuring that the horsts and grabens of its varied topography keep the pressure on the load bearing ischial bones and spare the more delicate tissues so often put in peril by the saddle. The shorts are finished with another trend, reflective detailing, albeit in a classically overstated Capo fashion. Instead of tags or small bits of applique print, the SL Bibs' entire compressive leg bands are reflective. Not only is this a large area for catching light, but it also moves more than almost any other part of the body while pedaling. While we don't necessarily have the results of clinical trials on hand to verify it, we're confident in the assumption that reflective surfaces in motion are even more noticeable than those that are relatively static.
