This is Axesquin's Futaezubon pants. The fabric is thick, so I think it's for Autumn. Size is S. The color is chestnut brown. I wore these when I was 172cm and 60kg. I wore them a few times for mountain climbing, but there are no noticeable stains and the condition is good. I also plan to list a thin Futaezubon (size M). Thank you.
