I bought this for work the year before last, but I'm selling it because I bought something else. The size is 01, which is a Small, but I usually buy M or L, so I think it's quite large. It's quite thick, so it seems like I wouldn't be cold even when fishing in the dead of winter in the middle of the night, lol. I bought it with a discount for 20,000 to 30,000 yen. Thank you.
