Review on Optimized Performance T-Shirt for Active Men by Nautica by David Causillas

This shirt is advertised as "young". Not sure if this means the size is smaller or the quality is lower. Maybe it means both. I usually find Nautica men's shirts very loose compared to shirts from other American brands. This shirt is closer to what I consider regular US sizing. I'm 160lbs and the medium fits me, relaxed fit but not as roomy as other Nautica shirts I've tried. The fabric is very thin; thinner than I expected from Nautica. Thin fabric can help keep me cool on a hot day but I don't think it looks very good except on the golf course or tennis court.
