This is a Patagonia Regulator R4 fleece. I bought it at a used clothing store a few years ago. Made in 2011. The color is blue. The collar and lining are gray, with a sheen like an acrylic blanket. I believe it has a structure where two types of fleece are bonded together, one for the front and one for the back. The pocket lining is mesh. It's well-made and cool, but... I personally found the lack of a drawcord a bit of a concern, and I haven't worn it much. I was wearing it with some room to spare, but when I walked, air would come in from the bottom and cool my stomach. I wonder if it's designed to be worn snugly. When I bought it, there was a spot about 5cm long where it was torn and the white side (of the fleece?) was visible. I remember a kind store clerk sewing it for me; it's on the back of the right shoulder. There were also three spots on the sleeves that were rough and dry, possibly from heat. Overall, it shows signs of wear. There were no other noticeable scratches or stains, but it is a used item. Thank you for your understanding.
