These are specialized riding pants, made in Italy, purchased from a riding club. They are a brand called "IAGO" and cost about 27,000 yen. Size is 38 (see image 7). They have non-slip material on the inner thighs. I've used them about 4 times. They have been washed, but there is a spot where mud splashed (see image 3). However, overall, I think they are in good condition. They were worn by someone who is 153cm tall and of average build. Please understand that there may be some overlooked details, and only purchase if you are okay with that.
