Outlast\xAC technology, originally developed for NASA, utilizes phase change materials (PCM) that absorb, store and release heat for optimal thermal comfort. Outlast\xAC technology is comparable to ice in a drink; as it changes from solid to liquid, it absorbs heat and cools the drink, keeping that drink at the desired temperature for longer. Outlast\xAC phase change materials work in the same way, but are microencapsulated to be permanently enclosed and protected in a polymer shell. We call microencapsulated phase change materials Thermocules\xBB.
This encapsulation process makes the Thermocules\xBB exceptionally durable for many applications. These Thermocules\xBB can be incorporated into fabrics and fibers and have the capacity to absorb, store and release excess heat. This gives any product containing Outlast\xAC technology the ability to continually regulate skin\xCDs microclimate. As the skin gets hot, the heat is absorbed, and as it cools, that heat is released.
Outlast\xAC technology is not wicking technology, which manages moisture by reacting to your sweat and pulling it away from the skin. Outlast\xAC technology will proactively manage heat while controlling the production of moisture before it begins. That\xCDs the Outlast\xAC difference.
