These are synthetic fiber pants from Integral Designs. They are warm and easy to use. I'm selling these because I got new pants. I'm 60kg and 174cm, and they fit me with a relaxed feel. They are size M. Also, I found a beanie, so I'll include it as a bonus if you want it. It's usable, but it has a fair amount of wear and tear, so please let me know if you don't want it. 》Additional Information I found a 5mm snag in the fabric on the back of the right knee. I apologize for this. (See the last photo) There are a few areas with some wear, but overall, I think they are in decent condition. Thank you.
