InGamba brand (a tour company) Omloop thermal bib shorts by Castelli.
Closest in build to the Castelli Omloop Pro, but slightly different roubaix fabric.

Size Euro medium = a U.S. size small (only reason for sale).
Worn & washed only once to confirm sizing.
These are awesome shorts, with a small pocket on the back.
Best when it's a little chilly, as these are not a thick thermal, and feel like regular race bibs.
