For me it's the first shirt "Compression". I must say that I am really impressed with the workmanship. The shirt wears great at running and keeps tidy warm. Sweat stains were not recognizable despite strenuous running and gray color, which can probably close to good air circulation.
The only drawback is, as with almost all t-shirts, the label with the washing instructions. There'll scratch something while running but I'll have to separate it out ...
