A Towel That Keeps Cold and Germ-Free

Nothing feels better than a cool towel after a hot workout. That's the inspiration behind the Kool Towel, a towel that stays significantly cooler than the ambient temperature around you, but requires no refrigeration whatsoever. Made from hyper-evaporative material, the Kool Towel is activated by water but always feels dry to the touch. The towel stays cool for up to four hours, depending on conditions, but can be reused several times before it needs a wash. The towel comes in three colors, is both antiseptic and antimicrobial, and is perfect for sports, fevers, or illnesses, or just relief from the hot summer sun.
Cost: $19.99 on KoolTowel.net.
