Familiarity: I've put it through the wringer
Yes, it is a $65 T shirt. But for hot weather, i have never worn anything so cool and comfortable. i wear hiking, yoga or just to work when it gets really warm. They only have a little give, and it is a 'Trim fit'. so if you like loose, you may want to up size.
They are very thin and light, scary so, but i have not torn one yet. Have 2.
