Mont-Bell XL size T-shirt set, pink and yellow. - Brand: mont-bell - Size: XL - Color: Pink - Color: Yellow Thank you for viewing. The above was written by Mercari AI. It's a women's XL size. I bought it at a real shop and wore it a few times, then stored it in a drawer. I haven't worn it much, so it's relatively clean, but it's a used item. Please refrain from purchasing if you are overly concerned. I bought it as underwear, but I no longer need it because I use Geoline underwear and Finetrack's Dry Layer. It's a women's XL, but it's about the same size as a men's M, so I think men can use it as underwear too.
