This feels comfy, haven't used in the heat for its intended purpose but also works as a helmet liner

Excellent quality I wear this under my hardhat at work every shift. I’ve had it now for over a year and it is no worse for wear or washing.

I have a large head and the fit isn’t comfortable for me in any way. Can wear for short periods of time but cause headaches after 10 minutes or so
