        Yup. The idea is that it protects your head from overheating. You wear it so that there is a pocket of air between your head and the hat, so it’s basically insulation.

          And it works! I won one at a local sauna marathon a few weeks back and you feel the difference when you take it off.

        Actually, many people (or even majority) don’t wear it nowadays. It’s a protection against heat stroke, and if one doesn’t visit a steam room one will be fine, though it’s optionally even in a steam room, e.g. I never wore it.

          Protecting against heat stroke potentially sounds like a good idea, but I also feel that preventing that may open you up to less obvious issues caused by being too hot for too long.
