I spoke with Six Six One to find out why supplies appear to be dropping.  I was told that the manufacturer has picked up a Federal contract to manufacturer Core Coolers for our troops in the Middle East.  Most of his resources are being taken up by this contract, and public supplies have taken a back seat.

We have done our best to buy as many remaining Core Coolers as we could, but colors are limited.  Remember, this goes under your mesh jacket, and most cannot been seen.  Color doesn't really matter.  Our advise, get them while you can.  There's no date when supplies will return.

In development for 2 years with Cool Tekwear, SIXSIXONE and Bob Hannah..... Used by fire fighters, first responders, military personnel, athletes and race teams, the SIXSIXONE Core-Cooler Personal Radiator™, works by utilizing the latest advances in Polycrylamide Cross-Linked Polymer technology.

PCLPs are non-toxic, hypoallergenic and completely inert plastics, which absorb liquids. The SIXSIXONE Core-Cooler's specific compound of PCLPs uptake water at a rate of 500:1. Soak the Personal Radiator in water for as little as 5 minutes, or up to 120 min. Allow to dry, Velcro the "SIXSIXONE Core-Cooler" on and stay cool for up to 5 days.

• The SIXSIXONE Core-Cooler PCLPs along with our special combination of fabrics create a two-stage cooling system keeping the user cool.
• Cools by evaporation, as water vapor is released around the upper body. The effect is an overall increase in energy and comfort.
• As the water vaporizes away, the SIXSIXONE Core-Cooler loses weight but maintains it's full cooling capacity.
• The inner liner poly-suede material gives a soft non-abrasive feeling and creates a heat sync against the skin, which rapidly cools heat radiating to the body surface.
• Fully hydrated will cool up to 5 days on a single soaking and weigh only 1-1/4 lbs.
• Dry to the touch after soaking and will not wet your clothing.
• Ergonomic shape makes for a comfortable fit.
• No need to refrigerate! Cools itself through evaporation.
• Soaking for 5-minutes will offer light-weight cooling power for a long moto or all day.
• 10 to 20 minutes will cool for up to 48 hours.
• 1-2 hours will fully charge and last up to 5 days.
