I have a bunch of "tennis" apparel... i love Adidas 365/Clima Cool stuff... but for other outdoor activities, i love Patagonia's line of clothing. So i checked to see if Patagonia had something that was close to my tennis stuff... and they do... The Men's Run Shade shirt, it's great!... i just played in one and this shirt feels great! It's slightly slim (nice fit) but moves so well on your body, it's very light and is loaded with "Patty" technology. Nice zip front collar, the seams are perfect (virtually unnoticeable), breathes well, moves well and holds shape... plus it's made from recycled materials... If you can, check it out... something different, and very well made from a great company.
