Short-sleeve swim tee featuring quick-dry UPF fabric, raglan seams, and exposed stitching; UPF 50 helps protect skin from the sun; Fits looser than a rash guard, designed for performance and all day comfort.100% Polyester. Dark Blue. I have 2 of these. 1 is NWOT. This one was worn once or twice and there is a small suntan lotion/oil stain in the back. It's the only obvious imperfection. Since the shirt is Navy Blue, it's not super obvious--please see last 2 pictures. Price reflects this. Size XL
