I rarely review but thought this product deserved one, which says something already. This button up is exactly what I was looking for. I am a firefighter that has many years of experience working in the brush with wildland fires etc. I wanted a button up “overshirt” for the ranch that was reminiscent of what I grew to love for project work on the crew. This shirt itself is slightly large, and is thicker and more “heavy duty” constructed than most pants. Most pants, like dickies for example are 9oz, this shirt is 12oz. Perfect for a work shirt. Not only can you rely on the beefy stitching, flawless seams, and thick material, but the shirt looks so good if you opt to keep it washed and clean you could easily wear it casually out and about. For my personal use I treat it like a chore coat, taking it off in the garage to hang up with my boots and hat/hardhat. It doesnt get washed except for extremely infrequently, building a patina of sorts, molding to my body, and wearing now more like armor than a flimsy shirt. For reference I am 5’6”, ordered a SM, which fit my stocky shoulders perfect. The sleeves were approx 3” too long, and the length of the shirt easily 5” too long. I took it to a tailor to fit it to me perfectly, since this shirt will easily last a decade and more, and will be the perfect investment to last me and work as hard as I do . 10/10. Absolutely recommend if you need a reliable shirt that will stand the test of time, with the history and tradition behind it that you can feel proud to continue on
