This is a rubbery feeling synthetic towel that actually works to cool down several degrees lower than the air around it, making it great for summer and working out. All you would need to do is dip it in any temperature of water and then the water would evaporate, leaving a cooling sensation. It is not big - perhaps the size of a hand towel. As it dries, it becomes hard and easy to break apart. You can leave it in the zip bag to keep it malleable - or a Tupperware container. Just ensure that it does not get moldy.

If you can find towels with same material for a cheaper price, it would be worth getting that as the technology is not exclusive to this company. It does work.
