Bought this shirt (in 2 colors) 2 1/2 years ago and it is the only shirt my husband wears for hiking. We go to Sedona a couple of times a year and in heat (high 80's) or cooler (low 50's) it is perfect for hiking. Breathable, flexible and easy-to-pack and the wrinkles fall out after unpacking. To top it off, it's very stylish-looking too so he can go from the trails to some fairly nice restaurants and not feel underdressed.
I bought this shirt for my husband, who was going bass fishing in Mexico. He loved it so much that he bought a second one for him and one for his son, who accompanied him on the trip.
I like everything about this shirt except the way the material feels. It's sort of clingy, especially when it gets hot. Seems to protect my skin from the sun, though, so Ii like that part.
