My brother used to run marathons, and this is one he actually ran. This shirt has been worn on many training runs since then though, and it does show use. The stains, while not severe by any means, are undeniably there. I tried to get them out in a load of laundry, and they may have faded a bit but I didn't get rid of them. Maybe your laundry skills are better than mine (not saying much). I tried to show them in the last three photos, but they just don't photograph well for some reason.

The size tag is VERY worn. I think I can barely make out that it's a large, and I can't imagine why he would have gotten a larger size, but PLEASE check out the measurements below to make sue it'll be a good fit for you.

Measurements, laid flat and not stretched:

Shoulders (between tops of shoulder seams) 20 inches
Chest (pit to pit) 21 inches
Bottom opening 21 inches
Length (from top of collar in back, to bottom) 25.5 inches
Sleeve length (along top, from shoulder seam) 7.25 inches

Material: 100% cotton

Let me know if you have any questions!
