  • Good quality
Size: X-Large Color: Green
I’m glad I finally found a shirt that will allow me to breathe in the heat.

  • Great Fit, Light weight
Size: XX-Large Color: Camo
Light weight perfect for summertime great fit. Only other thing I’d suggest would be for Knox to put the “Cat 2 & NFPA 2112 tags” somewhere on the shirt. Thanks for the free safety glasses ! Most definitely will order another shirt soon!

  • Light weight FR
Size: 3X-Large Color: Tan
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

  • Great warm weather FR!
Size: 3X-Large Color: Green
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. ... show more

  • Very light
Size: XX-Large Color: Wolf Gray
I melt in the summer in front gear and this is so light.

  • Worn for welding
Size: Large Color: Wolf Gray
My son has been in welding school in North Carolina in May. He says this shirt protects him the best from sparks and bits of metal/slag. He also says it’s lightweight compared to other shirts so he stays cooler!
