Just back from a VERY hot trip to Disney and I purchased the gel neck bands from Wal-mart for around $2.00 Let me tell you it was probably the best $2 i ever have spent. They really cooled you down. Every night we would put them in fridge. When we use them and the they lose there cool we would stick them in our cooler for about 30 minutes and get them really cold again and they would be good as new. They really took the edge off.
