I bought this about 10 years ago. I used to wash it with down detergent during the off-season (early spring). The size is L in JPN, which I think corresponds to M in EUR. I had the chest pocket repaired because it was torn. I think it's been used quite a bit. Although it's not torn, I think the down feathers inside have come out compared to when it was new. Please understand that this is a used item before purchasing. Additional information: I will compress the clothing in a compression bag before shipping. If you are not okay with this, please refrain from purchasing.
