This is a Patagonia Capilene Cool Daily Hoodie. The size is S, which is equivalent to a Japanese size M. I purchased it from the Patagonia official website, so there's no worry about it being a fake. It's authentic. This popular item is currently out of stock and unavailable for purchase. The advantage of this color is that it doesn't look overly synthetic, and sweat stains are hardly noticeable. I've worn it about twice. I washed it carefully before listing it. (No fabric softener used. No dryer used.) As far as I can tell, there are no scuffs, snags, or stains. The original tags are also included. I'm selling this because I have several Capilene Cool Daily items and am organizing my collection. I think this model will be useful in the scorching heat we've been experiencing. The size should be just right for those who usually wear S or M in Uniqlo or Montbell.
