The Mavic Cosmic Pro Men's Bib Short is Mavic's lightest bib, designed for the steepest climbs on the hottest days. From its lightweight but supportive main body fabric to its multi density 3D Pro insert, the Cosmic Pro is ready to help you tackle mid summer rides you wouldn't dream of going for in a lesser bib.Constructed from Skin Power fabric, Cosmic Pro Bib Shorts not only wick moisture to keep you cool and dry during blazing hot rides, but they also function as a medium weight compression fabric. This minimizes vibration in your muscles, which, in turn, reduces fatigue. Skin power is also extremely abrasion resistant, so the Cosmic Pro should last season after season. The shorts were sewn using a seamless construction and silicone leg grippers hold them in place so they won't creep up.The Mavic Cosmic Pro Bib Short utilizes Mavic's Ergo 3D Pro Insert, with multi density and variable thickness foam to provide cushioned support where you need it without unnecessary bulk. In addition, the entire chamois is covered in anti odor fabric, and it stretches to conform to your body shape so that it won't bunch as you ride.
