This is an autumn/winter knit cap from the hat brand arth. The size is 57-59, but it's stretchy, so it's easy to wear even for people with larger heads. Material: 70% wool, 30% nylon It's highly insulating and doesn't feel scratchy, so it's warm and comfortable to wear. I think this is a discontinued model, so it's the only one available. I purchased it around 2024 and have used it a few times. Please only purchase if you don't mind that it's been stored by a private individual! There are no noticeable stains, and the shape is still good, so it's first come, first served. Instant purchase is welcome. ⭕️
