Fantastic all around shirt!
I don't normally write reviews but I thought this shirt warranted one. I originally bought it because it felt light weight and I wanted something with UPF protection and long sleeves for gardening/outside house maintenance in 95F summer heat. Shirt is tough, holds up well to snags on twigs and rose bushes. I was so impressed with how the shirt functioned in the yard that I decided to give it a go on the trail. Hiking with long sleeves in the summer was a new concept for me and I was surprised by how well it preformed. It's not a mesh tank top but the additional sun protection added a real value. On top of the performance aspect of the shirt, my wife loves the way it looks and feels. I find myself throwing it on just to run errands around town. One caveat, I'm 5'9" 165lbs with an athletic build and I bought a size small, I was shocked. You'll probably need to try this on in the store to find your size.
Awesome shirt
Really like how soft it is and how cool you stay. I was walking on a trail and brushed up against a tree branch - I thought it would've ripped with how soft it is but it held up great. Good for starting hikes early in the morning when it's cool out and into the hotness of the day when it gets warm out. Wore this for the first time on a CO 14er and loved it. Definitely worth it.
No fuss comfort and style
Nice shirt for everyday wear, but pratical fabric for work, exercise, or play. Looks good, feels good. Washb and wear easily.
Super comfortable
I really like this shirt. It is very comfortable. It fits well and just the right weight for fall in the Bay Area.
I have lived in this since I got it.
Incredibly comfortable. Like an old thin well worn cotton tee. Great odor control for poly pro.
Greatest Shirt Ever Made! Not kidding....
Fits great. Looks great. Most comfortable shirt I own. I bought 2 more in other colors.
Love It
Great Shirt. Excellent Fit. Keeps me warm. My new favorite shirt until it gets warm.
