Frederick B.wrote a review of Castelli Free Aero Race 4 Limited Edition Bib Short - Men's on August 2, 2019
Me, 5-11, 164lb, usually a Large fits me in Castelli, ordered the large, overall too small (quads, hips and strap length). Ordered the XL, all good, probably will lose some of the compression on the quads, but very happy with them. Typical day in the saddle for me 40-60 miles, 3-5k of climbing.
If there is one piece that concerns me,it's is the mesh straps, they seem delicate.
