Patagonia Snap T Made with Polartec fleece, it's a good quality item that won't pill or get flattened. I previously received it on Mercari, and a family member wore it once. It's a Patagonia women's M size (equivalent to a Japanese L size), but perhaps because it has little sign of wear, or perhaps the previous owner wasn't very large, it doesn't feel significantly different from other women's XS or S Snap T's. While I say it has little sign of wear and isn't stretched out, there is a fair amount of pilling on the piping. No pilling is particularly noticeable on the fleece fabric itself. Color: TBX It's a nice, vibrant, beautiful bright red color. It's not orangey or pinkish. It's vivid and bright, but not quite neon red. Size Width (underarm to underarm): Approximately 48-49 cm Shoulder width: Approximately 39 cm Sleeve length: Approximately 57-58 cm Hem width: Approximately 50 cm The mannequin is a size 9. Size: M *Manufacturer's size is also women's M.
