DetailsLouis Garneau Men's Standard Fit Size Chart The CB Carbon Lazer Bib is constructed using 6 panels to create a compressive and ergonomic fit that is designed to support the body in motion. The design of the bib is combined with the use of highly stretchable and compressive fabrics which results in increased blood flow, reduced muscle vibration and, ultimately, reduced fatigue. At the thigh, an Aero Lazer band is used for a smooth transition that improves aerodynamics as well as muscle support. A coldblack® finish allows heat to be reflected by the fabric, unlike common dark textiles which absorb it, to prevent overheating during physical activity. The bib straps are made with both Carbon-X and Highlander mesh for great comfort and moisture evacuation.
