Whether you're a driver, crew member, spectator or just working around the house on a hot day, the Cool Collar can help to keep you comfortable for up to two hours. Charge the collar by placing in a freezer - this is not the dimestore variety soak-in-water and drip-down-your-neck cool collar! The cryo-core remains flexible down to -50°F. Buy several collars and rotate to stay cool all day. The removable fabric shell has one thick side and one thin side. An additional insulating layer on the thick side of the shell allows you to fine-tune the rate of heat transfer. Extended ends can be tied around your neck to keep the collar in place.
The NEW Techni-Ice core material is shipped in dehydrated form. This reduces the shipping weight, while also making it possible to send through the mail via USPS. Before the first use, the core must be immersed in water to reydrate. You only need to do this once. The Techni-Ice locks the moisture in, so you can enjoy cooling without getting soaked.
Note: Color and pattern may vary from photo. Sorry, no color choice.
