This Ryders shirt is acceptable, not great.  I had a Coolmax tshirt purchased for approximately $7 about 20 years ago, that lasted 20 years, with no color fade.

The Ryders shirt fits looser on me; which creates airspace that humid air can accumulate when the body is still.  My Coolmax old tshirt was skin tight, and as such, it immediately pulled the moisture off my body.  When one's moving or there's a breeze, Ryders is cooler than my Coolmax.  But, realistically, I "feel" the heat when I'm still.
