I think I have 11 of these GH Polos and this one is my favorite. So instead of writing a review for each one, here is just one. Trying to play gold in Southern Arizona in the summer months can be brutal, but these shirts are a game changer. The material is like made from the cooling towels so when you sweat or pour a little water around your neck, it is cooling....even in 100 plus degree temps in the shade. The flex is not so tight and moves with you smoothly without restrictions. I am 6' 228 athletic build and wear XL-XXL typically but these are oversized due to a golf polo, so order your regular size or go a size down. It fits great in the arms. If you have a beer gut then order your typical size....this shirt will help hide it! GH keep putting these quality shirts out there...and your competitors are trying but the quality isn't there. OH Thank you for the FAST shipping every time! MERICAAAA YEAH!!!!
