This is a sweatshirt from the 1960s-70s. There are no tags, so the brand is unknown. However, the material is cotton. I don't think it contains any polyester. It's a slightly thick cotton material. I think it's unusual that it's set-in sleeves instead of raglan sleeves. It's a two-tone gray. The ribbing is a slightly darker gray. It's hard to tell from the photos, but it has a vintage feel in person. From neck to cuff: Approximately 75cm Width: Approximately 59cm Length: Approximately 63cm
