I recently purchased this shirt, along with similar shirts from ex Officio and Mountain Hardware. While I do like all 3 them quite a bit, this one stands out. I bought the medium for this shirt and it fits well (dress shirt size is 15.5- 32/33).
The material is nice and the construction is sturdy. Nice and light weight, but appears durable so far. The Specs say "1 chest zip, 1 chest napolean", however, the one I got only has one pocket total and its hook and loop (velcro). The flap on the other side is just decor. The length of this shirt is perfect for me. Its long enough to tuck in, short enough to be worn un-tucked. The one and only thing where this shirt doesn't beet the others I purchased is in location of the button on the sleeve. On this shirt, its just above my elbow, meaning the sleeve roll is just below. Others I've purchased in this category have buttons higher up the sleeve. This is not a problem for me, but worth noting here. Also worth noting is that unlike the photo in this listing, there is no decal on the cuff (phew!).
