Summary: I am a little disappointed with the evolution of this line. It's a good shirt, but the styling is more stylistic and the venting seems a step back in quality. The material seems resilient, and that's why I purchase this line (at least in the past). Full review: I originally bought two Mountain Hardwear Canyon shirts and two Columbia PFG Tamiami™ II shirts for traveling to the Philippines on charity work. I needed to work in hot, rainy environments, yet still be presentable while speaking to government, church, and local leaders while on the job. A huge benefit for me was that these shirts do not show sweat stains, they breathe fairly well, and most of my stays were without AC in 95F, 99% humidity climates. The MH Canyon Shirts were a little more 'sporty' looking than the Columbia PFG's, but the material was thicker and seemed to be more resilient, so I wore them more often when working outdoors. Over the years, my older Canyon shirts have accumulated paint stains that I can't wash out, so I thought I'd buy some new ones. The older models had mesh underneath the armpits. At one point in the Canyon shirt's evolution you couldn't even notice the mesh vents were there, aiding in not wanting to look like I'm wearing a camping shirt around town. Here's the problem, the little changes they have made to this new line make it look like an ultra casual, camping shirt. Nice looking, but still like a camping shirt. Although the material is still thicker than the PFG shirts, the bright stitching thread is an attempt at style that turns into "this shirt is so casual it doesn't matter how it looks" type of style. It's a shame, since the material has a nicer appearance than the older ones. Additionally, the arm vents are no longer mesh, but basically a big hole that is sewn in 4 spots (forming three little holes). I worry that this area is more of a weak spot than it was before. Lastly, the colors are now 100% camping/fishing shirt colors. Instead of the nice midnight blue color, its now an ultra-dark, aqua color. I don't know if I will keep following this line after the last iteration. If you don't need slightly heavier material and you prefer a more traditional, toned-down look, I much prefer the Columbia PFG Tamiami™ II long sleeve shirts to these (White and Navy). The Columbia Silver Ridge Lite line is nice too. However, both of those shirts use lighter material than the MH Canyon shirt which might be less resilient if you are working/active around cement, bricks, rocks, heavy tools/equipment, etc. In the meantime, I decided to keep using my old Canyon shirts with the paint stains on them instead of replacing them all. One of these new Canyon shirts is enough.
