This is a Patagonia Merino Wool Capilene Air Crew. I've only worn it a few times indoors. It's thin but still warm. I thought, "That's Patagonia for you." There are no noticeable stains. There are no frays or tears, and I think it's a beautiful item. However, please understand that it has been used, even if only a little. Please check the condition from the photos. Regarding the size. Please consider this as a reference only, as it's a rough measurement by a layman with a tape measure. Length: 71cm Width: 48cm Sleeve length (from the base of the neck to the sleeve): 85cm The tag says M. I live in a smoke-free environment and don't have any pets, so I don't think there are any odors. Thank you very much.
