See description in photos off of Everlane’s website. This is last year’s version of the heavyweight work shirt. Super comfy, thick, structured material - can be worn as a button up or a jacket. Really handsome blue color (a bit more of a true blue than the navy shown in stock photo) and in great condition. My husband typically runs large to XL but this large feels just a bit snug and he likes to layer. He’s worn it only a handful of times. I’d say if you run med-large this is perfect. Smoke free home.
