Nike sweatshirt! Nike brand. Vintage, white/light silver tag (can't really tell which color, sorry! I included a photo for you to check).
Color: Green, similar to a dark sage color
Size: Medium (measures approx. 22 inches pit to pit, 26.5 inches front length)
Super comfy, and in really good condition for its age! Has one faint mark to the left of the design, but it's barely noticeable when wearing.
