I just want to post a word of warning on Chilly Pads. I've had so many people rave about to them to me, that I thought they were the answer for my daughter, who is always hot. She is not allergic to anything that I know of. She used it for the first time a few weeks ago, and immediately broke out into a horrible rash, of red, raised bumps. We immediately stopped using the pad, but the rash lasted for nearly 2 weeks. When I looked into it further, I noticed a few people in the
Amazon reviews also have complained of having allergic reactions to the material, despite never being allergic to anything before. Interestingly enough, I contacted the company and they told me they had never heard of that happening before, and yet, according to reviews on Amazon, their website had once said that the material could cause a rash.
So, my advice is to test it out for a short time before your vacation because the heat stinks, but having a red swollen rash on your vacation stinks worse.
