This is a Patagonia M's L/S Back For Good Responsibili-Tee purchased in April 2021. The size is S (US size), and the color is GHBI (Gravel Heather w/ Bison), which is basically gray. (The close-up images, like the second one, show the actual color more accurately.) As I mentioned in the listing for the navy one, I'm selling this because my preference for the fit has changed, and I haven't been wearing it. There's some pilling, but it's not very noticeable due to the color. Width: Approximately 47cm Length: Approximately 68cm
