Castelli Free Aero Race 4 Limited Edition Bib Short Men’s

Why We Like The Free Aero Race 4 Limited Edition Bib Short

Designed to cheat the wind, the Free Aero Race 4 Limited Edition Bib Short as it’s top-tier short for training and racing. We love it particularly for how well it handles the heat, allowing us to ride in the hottest weather. The Limited Edition designation pertains to the use of colors that distinguish it from the standard Frees. Comfort, aero benefits, and strikingly good looks, all in one package.

Inside the bib, the excellent Progetto X2 Air chamois has a seamless construction, four-way stretch, and impressive ventilation with its perforated foam layer. The Forza material of the legs offers just the right amount of compression to aid in recovery and prevent premature fatigue over rougher terrain. The Doppio V construction allows for excellent breathability without sacrificing support while the suspenders are mostly mesh and utilize lie-flat material on the shoulders. For the leg openings, Castelli trusts its Giro 4 mesh-like grippers to keep the hem in place.
