This is an initial impression, will revise if anything changes down the line.

The fabric is excellent: light, stretchy, breathable, wicking, and comfortable. The size is true to fit (6' 2'', 190lbs, large fits well, as expected for a large). I feel I have full mobility for any activity, without any movement restriction.

I'm very pleased, with only a few small criticisms. The bands used to roll up the sleeves, work well, but are unnecessarily complex. Rather than putting the tab thorough a loop on the sleeve and then buttoning the tab to itself, why not just button the tab to the sleeve directly like other similar shirts? It's easier and works just as well. The large vents on the sides of the back, while appreciated for keeping cool and dry, are also a little too big. I can put my whole hand through to the mesh. Might be nice to add a few more anchors on the back vents so they aren't as wide open, and more subtle. Lastly, the small piece of velcro that fastens the chest pockets closed feels a bit cheap on an otherwise excellent shirt, I would prefer a button, or even zippered pockets.

Aside from these minor criticisms, this is the best shirt of its type I've found so far, and at a lower price than many competitors. I'm satisfied with my purchase, and will probably purchase more.
