I bought this shirt my hubby. The material is thick but airy and helped alot to control sweats.
For the sizing part, alot of the comments to take 1 size bigger but I'm glad that I bought the actual size. If you do not have a gym type body (super broad shoulder and pumped arms], I would suggest that you stick with the actual size.
I didn't 5 star due to the collar part, I think when it rubbed the neck/hair area, there is these pesky fabric pills (puff). The thing is I hand washed it every time with gentle hand scrub and without twisting the shirt.
