Swiss Tech Men's 2XL Olive Green Long Sleeve Button Up Shirt There appears to be a small mark on the right side of the collar, but I honestly couldn't see it until taking a picture with the flash on. I tried to get photos showing how color may appear different based on lighting. It is a dark greenish gray color heathered with beige/khaki color. Very nice material for being outdoors or fishing. #menswear #outdoor #hiking #fishing
