The black one has a dark spot seen in the photo with my hand by it. Listed price lower to reflect that The Navy Blue shirt is in fantastic condition. the black shirt is a little thicker in the material feeling and the blue one thinner. If you know Salty Crew. then you know they do shirts sometimes in a lighter cotton feel and thicker. For us, the thicker ones always seem to run smaller, as you can see in the measurements. black shirt: 16 3/4” chest & shoulder to bottom hem 25” & sleeve length 21.5” Navy shirt: 17” chest & shoulder to bottom hem 28” & sleeve length 24”
