Love the shirt. Breaths great, Looks great, good sun protection, dries fairly quick, and very comfortable. Runs a bit big in my opinion, but I'm sort of in-between sizes. My only complaint is that I have a hard time getting the wrinkles out. Besides that there are no complaints.

I wasn't sure how much I would like this shirt, I am a merino maniac when it comes to mid-layers, but I quickly found it to be indispensable. It is a great layer because it is versatile. Provides a little warmth on a cool morning, and keeps the sun off you in the hot afternoon, keeping you cool. If it gets too hot, roll the sleeves up using the convenient button and loop attached to the sleeve. It handles sweat well, and dries out lightning fast, even after a complete soaking (much faster than my merino layers, I must admit). This (along with my Smartwool midweight) has become a layer that I take on every backpacking trip, regardless of the season. The fit is good, go by the sizing chart.

I use these for desert hiking. I actually stay cooler when I keep the sun off , so I wear this shirt and a pair of polypro hiking pants. Shirt is true to size (M) for me.

Very comfortable fit. I took it on the last camping trip and it was the only shirt I needed. Felt good under a pack as well. And it looks good enough to just wear around town. Great Buy.

fantastic shirt, lightweight, dries super fast. i have been wearing throughout the s.pacific and have washed it numerous times in a sink, and dried it by wringing out and hanging over a pack over night. only one caveat, it is a little tight across the chest, (when compaired to other columbia shirts) especially when wearing a pack... otherwise it would be perfect.
