Placing a premium on go fast functionality, the Attaquer Men's Race Bib Shorts feature an ultra slim, compressive design that hugs your body for maximum support. Primarily designed for racing, compression Lycra stabilizes key muscle groups for maximum endurance through crit races and staged events. Its highly breathable, lightweight design keeps you from overheating during sweltering summer conditions. Narrow cut bib straps bolster support without causing irritation or soaking you in perspiration. And to keep chafing from slowing you down, flatlock stitching sits smoothly along your lower body for blissful comfort, mile after mile. Absorbing fatiguing road vibration, the Quad Density chamois keeps you riding smoothly across jarring road surfaces and long distance efforts. Embedded carbon threads accelerate moisture transfer, eliminating the damp, sweat soaked feel and undue irritation during high intensity racing scenarios. Moving on to the rest of the shorts, silicone leg grippers retain a secure fit without them riding up, especially during fast pedaling movements. UPF 50 protects your lower body from searing UV rays when you're riding on the sunniest days of the year. Rounding things out, reflective details enhance visibility to passing vehicles after dark.
