UPS brought package yesterday, I immediately put the Chill-Its on, as it is steaming hot right now and I have extreme problem with a flood of sweat flowing off my bald head and neither ball cap or bandanna stops the aggravating flood. Within 5 minutes in the bright, hot noon-day sun I knew I had made one of my most important purchases of the year and just ordered several more Chill-Its. Thanks a bunch!!
