This shirt has a compression fit. The fit is very similar to my Under Armour cold gear but just slightly looser. I wear a large in the Under Armour and the 5.11 holster shirt in large fits perfectly. I thought this should be mentioned since none of the other reviews mentioned fit.
Pros: comfortable, conceals weapon very well,
