PCM Cool Collar


The EZ Cooldown Cool Collar is an affordable and effective phase change cooling aid for all situations. The Cool Collar is available in small and large as well as in two temperature ranges

Wrapped around the neck, this PCM collar helps cooling the arteries and veins which run close to the skin’s surface. This makes the neck one of the most effective places to cool your body.

The EZ Cooldown Cool Collar provides hours of comfortable cooling and helps to prevent heat stress thanks to the special PCM insert. The PCM insert is able to provide cooling relief for up to 2 hours even under strenuous activity.

A stretchable Velcro closure ensures a comfortable fit.

Each EZ Cooldown Collar contains a biobased phase change material (PCM) pack which retains cold at 15°C (59°F) or 21°C (70°F).

Choosing a PCM Temperature 

When you need maximum cooling for a short amount of time, choose the 15°C (59°F) Cool Collar. 
When you prefer longevity over absolute cooling ability, go for the 21°C (70°F) Cool Collar.
