Super nice shirts but they run really big. I normally wear a large and I should have gotten a Medium.

I was very surprised with the quality of these shirts. Compared to the cost of other brands, it would be understandable for them to not be as nice. But these are hands down the most comfortable FR shirts I’ve worn. Worth every penny and judging from the quality of the stitching I expect them to last a long time. 100% recommend. I will be giving Knox my business for work clothes from here on out.

Great shirt light weight. Maybe the lightest shirt I own now. I wish it had a pocket. Put a pocket and its a 5 star. Coolest FR I own for hot weather. Also very soft and comfortable

First time I wore them, they were very thin but comfortable. I wanted to get them for my welding labs at school. First time I struck the arc on my stick welding rod, spatter went on shirt and got burned. I got burned 6 more times as I had enough and told my instructor I’m going home. Don’t buy these, they don’t protect you. I guess they are just for looks and advertising. I can’t believe I spent money on shipping for 4 shirts of garbage

Bought for husband because our last name is the same as the product, ha ha. Nice looking and he needed a few new FR shirts, so I got one to try this brand. Went one size up based on other reviews. He LOVES this shirt and I have ordered more in different colors. Lightweight and good for warm days, ideal for Texas summer. Definitely good that we went up a size. He did wear it on a cold day too and had to layer to stay warm. This is for sure a lightweight option.

I will probably order a medium because the large was like an Xlarge
