Why are there five different types of cooling packs???
ThermApparel Cooling Packs each serve an individual purpose to make the best fit for your cooling needs. From SlimCool to Grab-n-Go, check out the descriptions, specs, and uses below.
Our Tech
Our cooling technology in the Cooling Packs is Phase Change Material (PCM). Why PCM? We chose this because it's the best. The PCM we use is non-toxic and biodegradable, not petroleum-based. Our Cooling Packs cool no matter the conditions. It works through conduction (making contact with your skin) to cool your body.
Think about how fast you cool down after jumping into a cold swimming pool; that is conduction in action. Unlike cooling towels and evaporative vests, PCM doesn't need evaporation to cool you down. It works whether it's humid when there is no evaporation or in the desert, where evaporation occurs so fast that cooling doesn't happen.
Because our Cooling Packs are designed to start melting and refreezing at 70°F / 21°C, they won't sweat, making you and your clothing or costume wet.
Ice vs PCM
Our Cooling Packs are not ice packs. Putting ice directly on your skin is dangerous. Ice is too cold and will damage your skin if left on too long (think frostbite). ThermApparel Cooling Packs are not as cold as ice and are safe against the skin for long periods without batteries, pumps, wires, external coolers, or noise.
Ice and other cooling vests require a layer or two of clothing between them and your skin to help prevent frostbite. Putting freezing ice and gel (clay and water with antifreeze) packs on your skin interferes with your body's natural cooling system.
When something cold is introduced to your system, your body automatically tries to warm it up. Now, your body is using precious energy to try to cool down some areas while other areas are being warmed.
Our Cooling Packs work with your body by cooling your blood as it passes the Cooling Pack. This cooled blood then circulates throughout your body, helping to maintain a cool core temperature.
ExtendedCool Cooling Pack
(2-4 hours of cooling)
ExtendedCool is the iceberg workhorse of all Cooling Packs because it provides the longest cooling time and is made of three connected squares that articulate and conform to your body.
ExtendedCool can also be used interchangeably in our three main products: UltraCool, RallyWrap, and UnderCool 3.
TIP: If more than 1-2 hours is needed, get an extra set of Cooling Packs so you can continuously change them out. The depleated Cooling Packs will refreeze before the new set melts, with ice and water in a 3 gal zip-lock bag.

SlimCool Cooling Pack

Made for UnderCool 3 only, it gives users of the UnderCool 3 the choice of cooling power or stealth cooling.
TIP: If more than 1-2 hours is needed, get an extra set of Cooling Packs so you can continuously change them out. The spent Cooling Packs will refreeze before the new set melts, with ice and water in a 3 gal zip-lock bag.

FlexCool Cooling Pack - Headband
(1 hour of cooling)
ThermApparel's patented tech makes FlexCool the head of the pack. It allows it to bend and curve around your head. The curve makes for more effective conduction, which equals more cooling in a smaller pack.
The Headband only fits FlexCool and requires 2 packs. It can be recharged in the refrigerator, or ice water. Do not freeze below 32°, or it will not bend and form to your head.
TIP: If more than 1-2 hours is needed, get an extra set of Cooling Packs so you can continuously change them out. The spent Cooling Packs will refreeze before the new set melts, with ice and water in a large zip-lock bag.
