This is a heavier-weight shirt than the standard inexpensive tee. The material is a bit stiff, even after washing. As with most of the Amazon brand shirts of various types I have bought, the sleeves are a bit shorter than I would like. Both the sleeves and overall length are shorter than the Russell Athletic shirts I usually buy, although this cost quite a bit less. The fit is also a bit more snug, so I would say it runs just a bit small.
