Lululemon Swiftly Tech Short Sleeve gray with yellow stitching

We made this run shirt to go the distance - literally. The body is seamless to minimize chafing during long runs and the fabric is anti-stink so the only output we're worrying about is our wattage. Lightweight fabric and seamless construction keep you moving freely I think this is a 6. The size dot is worn off. See photo Measures about 15” across. See photos. Very good used. No smoking. No pets.
