At first I was hesitant about the shirt. Have not been the biggest fan of TNF, but they have a few products out there that fit my needs and find their way on some trips. While trying this on at a local store, I first noticed the fabric was much thicker than the women's version that I had bought my girlfriend. The sleeves were also longer than every other shirt I tried on.
My first hike with this was on a 6.5 mile round trip with 2000ft elevation gain in 70+ degree weather. At the summit, my shirt was much drier than I had anticipated. I normally put on dry clothes at my destination, and left this on my pack to soak in some sun and dry; which it did in a short amount of time. I normally sweat a lot, and this shirt does an amazing job at wicking moisture from your body and evaporating it quickly. I have used many Nike, Adidas, Helly Hansen, Kappa, Patagonia synthetic fabrics, but this one blows them away in performance. I will see how this handles repeated abuse/rub from my backpack.
With my pack on, I truly noticed the length of the shirt. It is longer than I am used to, but after my third trip, I appreciate the long cut. I'm 6'1" and have now found a shirt that does not find its way above the hip belt while hiking. I consistently have 3" of shirt below my hip belt, and it stays there. The cut could be a little slimmer, and the sleeves shorter, but these are just personal nitpicks.
This shirt is now my primary hiking shirt due to its superior wicking capabilities.
