The FR Skull Cap is made from super soft inherently FR blend. It's breathable and offers excellent warmth and has a whopping 36 cal rating.
The Skull Cap can be worn under a hard hat or welding mask in the field or while skiing! The Skull Cap is indistinguishable from a premium store bought knit cap. It's made in the USA from a double layer circular knit. The seamless tube gives it comfort, stretch, and recovery. It will not "Shrinkwrap" your head like others on the market. If you prefer a classic ski hat with a brim try the FR Beanie. Unconditional Lifetime Warranty, just don't lose it. If you are looking for a classic FR Beanie with a folded brim, click here.
