Castelli's Aerorace Bib Shorts. Used about 5 times and stored. The tags have been cut off because I didn't like them. Please see the manufacturer's website for details. They are lightweight and extremely comfortable. They also have high-quality padding. The latest version's retail price seems to be 30,000 yen. Since these are used, please refrain from purchasing if you are sensitive to such things. There may be oversights, so please be sure to confirm any unclear points in advance.
