I've just bought wicking polo shirts by OR, Patagonia, Columbia and TNF to compare in summer heat/humidity. I'm in construction management and work about 75% of the time outside, so staying relatively cool and dry are the goals, while looking stylish is a highly sought after bonus. I'm 6', 175 lbs with athletic build and live in Alabama. Ordered the medium (great fit on me) and after a couple of wearings this seems to be a great shirt. Fits and wicks moisture well, very soft hand, extremely comfortable. The material is very thin (you can see through it when held to a light) which seems to help it's cooling abilities. I just ordered another one of these shirts, they look great. Other reviewers are correct, there is no chest pocket (not sure why the description says there is one) but no worries for me there. Highly recommended shirt, will update on durability toward the end of the year.7/15/16 Eureka! I found the zippered pocket, it's located on the right rear side of the shirt. Small but pretty cool for a credit card, cash or key if you wear the shirt untucked. I ordered another of these shirts in a different color, still working great for hot, humid weather.
