Mission Cooling Skull Cap- Hat, Helmet Liner, Running Beanie, Evaporative Cool Technology, Cools Instantly when Wet, UPF 50 Protection, for Under Helmets, Hardhats, Running, Football

Works fine. Fits my 8 yr olds head good. He wears it under his football helmet.

E' leggerissima.Non ci si accorge di indossarla.Tiene veramente fresco. La consiglio come sotto casco ma anche per chi lavora sotto il sole.

Works. Feels cool when sweating,

Great idea and it certainly makes a difference on a hot day

I live in the desert and I use this in my garage when doing woodworking or other activities there when it is hot. It would be perfect if they would make it in a couple of sizes, like Small/Medium and Large/XLarge. I have a big head and this is tight. It will gradually stretch a little bit, but one a little larger would be appreciated. I have several Mission Enduracool products, and they work well.
