A sporty fave (a former gym go-to of mine)! Super cute gray/white/black polo oversized "Pro Training" cropped top by Umbro purchased from Urban Outfitters. Super thin and lightweight, material is polyester. Women's size M (oversized) but fits a tad bit smaller due to some dryer shrinkage over the years. Preowned/used but in great condition (no major stains or pillage, see photos)! Outfit suggestion: black or white Fabletics keyhole open-back sports bra, black or white leggings, your favorite pair of gym shoes!
