Review on Optimized Propper Regular Fit Short Sleeve Performance Shirt by Charles Osguthorpe

I can't say enough good things about these shirts. They fit great. They are cool in summer but still cool in winter. They fade when you are in the sun a lot, which happens with almost every outfit. The sleeve cuffs and collar don't seem to fade with the rest of the shirt, so if you work a lot in the sun you'll end up with a two-tone shirt in a year or two, but the durability definitely makes it ready for that. I can't tear these shirts apart to make them last long enough to go away. Overall a great product.
