I am a Large and these shirts fit well. I'm very picky. I use these shirts for running. Fall is here and shopping at the store is very expensive. You can't find a price this good for shirts in a store. Definitely worth the wait for them to arrive. The quality was better then what I thought it would be. I haven't owned the shirts long enough to see how well the moisture wicking, and sun protection work. So with that being said I can't comment on that quite yet. Overall this is a good purchase and I may purchase it again later.
