Purchased used and used only once in a race. The size was apparently printed on the inside, but it's faded and unreadable. It's supposedly a size M. Back zipper type. I am 169cm tall and weighed 63kg during the race, and it was a perfect fit. There are no major noticeable scratches or stains, but there is one small spot on the mesh fabric on the back (photo 3), and one tiny spot less than 1mm on the lower left chest (photos 4 and 5). #Triathlon #TriSuit #TriathlonWear #TriWear #Men's #Sleeveless #LongJohn #BackZipper #CASTELLI #SizeM
