This ultra-versatile cooling band works with special technology that cools your skin roughly 30 degrees below its average body temperature when you get it wet.

Simply dunk it in water, wring it out, and wrap the band into any of its 12 styles including a headband, scarf, neck gator, hood, balaclava, cap, face mask, and others. Once wet, it will stay cool for hours.

The band is pre-shaped into a full circle which means you'll never have to fuss with tying or adjusting it. As a bonus, its made with fabric that offers UPF 50 sun protection so you won't burn either.Made with dual-strategy cooling technology, this sporty baseball cap combines an inner layer of HyperKewl fabric with an outer layer of water-repelling nylon. The result is that the inside portion next to your skin cools you down while the outside section keeps you dry and less sweaty.

The blend of fabrics makes it perfect for active pursuits such as running, biking, hiking, and other activities where you work up a sweat. Each time you soak the cap in water, the material stays cool for an impressive five to ten hours.
