Thank you for viewing. This is a Castelli bib shorts. Size M, I am 170cm and 60kg, and the size was just right. I have worn it 10 times and stored it in a chest of drawers after home cleaning. It is comfortable to wear and I didn't experience any chafing. Instant purchase is welcome. First come, first served. No claims and no returns after purchase. Please refrain from purchasing if you do not understand that this is a used item, if you are particular about details, or if you are looking for the quality of a new item. Thank you. #Castelli #Roadbike #castelli #BibTights
