i thought this base layer was going to be a bit too meshy and possibly a see through garment. no way!!! it is my new favorite go-to base layer AND non-base layer shirt. it fits just right...not too tight and not too loose. freedom of movement is smooth, and it breathes wonderfully. the orange color is rich and subtle which equals beautiful. i am 5'712 128 pounds and the medium fits me perfect. price was right...should have ordered 2 of them.
