It's always been a goal of mine to make modern-cut clothing and accessories out of historic camouflage patterns. It goes without saying that it's not always the easiest or most cost-effective project, but once in a while, I get lucky. These boonie hats are made by a very experienced hat maker out of 100% cotton Herringbone Twill material, like a lot of the original Dot 44 uniforms were. This makes these hats not only look great, but also gives them a lot of durability. I love mine, and wear it outside pretty regularly. It's become one of my favorites due to the comfort, style, and durability. Approximately 2 1/2" Brim Width.
