Really good value for money. I ordered one to start and ended up ordering 3 more. It's thin, lightweight, and the moisture wicking fabric works extremely well. I sweat easily but it dries up quick on this fabric without leaving behind any smells.
I get cold really easily so the shirt by itself on a cold morning (~15 degrees celsius) isn't quite enough. A thin-ish fleece jacket on top of this shirt would be sufficient.
