Decided to purchase this shirt based off prior experience that I had from donning and hiking in a short-sleeve metal-button ExOfficio shirt, the name of which is eluding me at the present moment.
In any case, I was floored not only by the durability of this shirt, but by the comfort and fit. From the moment that I slid this puppy over my shoulders, I knew I had made a solid choice for upper body wear.
The venting that is sewn into the shirt from the bottom hem up to the cuff around the wrist is magnificent, and never once ripped or tore even when being thrashed about in innumerable washing machines, or snagging on sharper brush when having to do a bit of trail blazing.
While backpacking, there were not plenty of opportunities to utilize the chest pockets often, but when I needed them, they were capacious enough to store gewgaws, doodads, cash, an ipod, sunglasses, power bars, and the like; nothing substantial, but things that one might like to have close at hand, for whatever reason. One primary factor that I truly reveled in was the fact that the pockets were not totally in the way of your pack chest strap. Certainly, there was some slight overlap, but nothing major enough to get you heated.
Overall, the preeminent factor that impressed me about this shirt was the fact that despite hiking over 1,200 miles in it, I can honestly say I would have to really study it to find any sort of staining from salt, sweat, or color bleeding from other fabrics that was a big problem with other shirts in the past. Small ones probably exist, but this is one incredible combination of style and fabric that went into the design and production of this shirt.
Regarding casual use, perhaps lounging on the beach while someone feeds you skinned grapes and fans you with palm fronds, definitely workable. The roll-sleeves are absolutely clutch, and made for a quick and easy conversion when I got hustling, I intend on getting another one or two of these to have for when I'm not hiking.
