Outlast® technology is known as a phase change material or PCM for short. It absorbs, stores and releases heat to provide the ideal temperature for comfort.. Outlast® technology works as they are microencapsulated to be permanently enclosed and protected in a polymer shell. Microencapsulated phase change materials are also called Thermocules™.
This gives any product containing Outlast® technology the ability to continually regulate skin’s microclimate. As the skin gets hot, the heat is absorbed, and as it cools, that heat is released.
Outlast® technology is the only phase change material that carries the Certified Space Technology™ seal of approval.
