Bests & Worsts Reviews from Amazon

This neck wrap may work in Riyadh or Denver, but not in Houston. Even if you use cold water, the wrap will only stay cool for about 10 minutes once outside in 90+-degree Houston evenings. I had better results wrapping ice cubes in a bandanna and tying it around my neck. Also, what does "do not over hydrate" mean in the Instructions? The thing never dries, which makes me suspicious that I'm essentially wearing a bacteria farm around my neck while jogging.
