Thank you for looking! This is a cold weather shirt from "Polo by Ralph Lauren," from the late 1990s to early 2000s, with an old tag. The design is similar to LL BEAN's chamois shirts but with a modern silhouette. The design features moderate distressing and a green and black shadow check pattern, giving it an RRL-like atmosphere. There is no quality tag, but it is likely made of cotton. Although it is labeled L, it has a tight silhouette, so it would fit someone who usually wears S to M. Please check the photos for approximate sizing. If you have any questions, please feel free to comment. Thank you for your consideration.
