Athleta Long Sleeve Running Top/Tee/Shirt Size: Large Color: Turquoise (brighter than in pics) Condition: GUC I'd say it runs more like a Medium. I'm a Medium and this is comfortably fitted on me. It is a seamless knit, so don't be alarmed if it looks small pit to pit - it stretches comfortably, it's just the nature of the knit. Has thumbholes. Beautiful turquoise color. Worn but lots of life left - only flaw is fuzzies on the inner left sleeve (last photo). Pet and smoke free home.
