Purchased at an authorized Gold's Gym location. It was in a package, and I bought the M size thinking it would fit perfectly, but it was too big for me, so I'm selling it. This is a comfortable T-shirt made with fine-count, high-quality yarn. It's in good condition, having been worn about 4 times. I'm looking for someone who can wear the following actual size measurements. ■Size: M ■Material: Body: 100% Cotton, Ribbing: 98% Cotton, 2% Polyurethane Actual Size (cm) Shoulder Width: 52, Sleeve Length: 24, Cuff Width: 19, Body Width: 56, Length: 64 *Please allow for slight variations due to amateur measurements.
