Runs super small

I returned this product before using it

I owned XXL Castelli bib tights from several years ago, so I ordered the same size in the Free Aero tights. These things were like knickers on me. Disappointing because I really liked my older Castellis. They must have changed their sizing chart or cut. Like the previous reviewer, bottom of the legs was loose (but not too bad). Material and quality seemed fine. As usual, Competitive Cyclist customer service was awesome and helped me find another brand.

Free Aero RC Bib Tight

I returned this product before using it

awful, disappointing fit. straps too short, too tight, limited stretch. lower leg material below the knee was loose fitting. several different panels/materials seemed together - just odd looking and odd fit. the fit from above knee to waist was good but the rest was a miss. 6' tall, 165lbs. normally wear large in Castelli, bought large. didn't wear outside, can't comment on warmth or water repel claims.
