Amazing bibs!

I am a tough customer when it comes to bibs. I can guarantee that I am the pickiest around. The Free Aero Race 4 is PERFECT. There is no shifting, bunching, pinching or other annoyances with these. Super compressive without the dreaded sausage leg. Breathable fabric and minimal branding, so that one doesn't become a moving billboard. Chamois is top notch!!
