This is a Patagonia Snap-T. It's from the 1980s, with the triangular tag on the collar. It's a rare, made-in-USA piece, and unlike current models, it has set-in sleeves. Also, unlike the reissued versions with two-tone colors, it has a simple design without a chest pocket or flap. The color scheme is very 80s, with fuchsia and turquoise blue accented by yellow. The size is L, but it fits like a modern M. I'm 170cm and 60kg, and it fits comfortably without being too big. There is no significant damage, and the condition of the sleeve cuff piping is good, as shown in the images.
