Choosing a PCM Temperature 

When you need maximum cooling for a short amount of time, choose the blue 15°C (59°F) PCM packs. 
When you prefer longevity over absolute cooling ability, go for the yellow 21°C (70°F) PCM packs. 
Next to these standard temperatures, we manufacture PCM packs in other temperatures on request, ranging from 6.5°C (43°F) to 29°C (84°F). Please contact us for details.

Choosing a PCM Configuration

As well as different temperatures, we offer PCM packs in two different configurations: 
The 8-cell packs are thin and flexible. They’ll move with you but offer less cooling longevity compared to the 4-cell packs.

The 4-cell inserts contain approximately 35% more PCM so they’ll keep you cool for longer. 
They’re a bit thicker than you 8-cell packs
