I just ordered a 4 pack. Anyone ever use them? I get hot in the sun, even in the 80s, and need more than just a funky sun hat, especially for when we start going to the desert (minimal shade). I also saw a review where a dog wore a cooling towel and the customer loved it for the dog! We have the dog issue too. Besides carrying a water bottle and maybe using a cooling towel, any other hints to stay cool while outside? Thanks, if any feedback.
