Lululemon men's size small black polo.  Size tag removed but was a small- see measurements below.  Collar has a button underneath so it buttons down but you can't see the button from the outside. In overall good condition with some light fading, no stains tears holes or piling.  No fabric tag but it does feel cotton like. Maybe a cotton blend with a little stretch. This is thinner and lightweight material. Stored in a smoke-free environment.
