Outlast® technology was originally developed for NASA to protect astronauts against temperature fluctuations in space. Outlast® material is a microencapsulated phase change material (mPCM) that can be blended into compounds suitable for applying to fibers, fabrics and coated materials.

Outlast® materials have the ability to interact with your body to help balance temperature by absorbing, storing and releasing the heat that you produce and maintaining a comfort zone.

The Outlast® difference

Products incorporating Outlast® technology continuously interact with the unique microclimate of the human body and the environment to moderate temperature from being too hot or too cold to being just right.

The human body naturally sweats to cool the skin, reducing the ability of clothing, footwear and bedding to keep the body dry and comfortable. Outlast® technology, conversely, will keep individuals comfortable by absorbing body heat when too much is created, thereby diminishing the amount of moisture. Here are a few more examples of features and benefits of Outlast® technology:

Frequently asked questions

What is Outlast?
Outlast® technology is the original temperature-regulating technology. Outlast® fabrics, fibers and coatings are ingredients found in everyday products and high performance gear such as bedding, footwear, apparel, outerwear and accessories.

How does it work?
Outlast® materials balance your temperature through the use of patented microencapsulated Thermocules™ that absorb and store excess heat, releasing it when you need it most.

Will Outlast make me warmer?
Outlast® materials continuously adapt to your changing thermal needs. In effect, Outlast® materials balance your temperature by reducing overheating and therefore perspiration, resulting in less chill and more comfort.

How is Outlast different from other temperature-regulating technologies?
Outlast Technologies, Inc. holds the patent for the original temperature-regulating technology and ingredients for fibers, fabrics and coatings. Many products in the marketplace claim to have temperature-regulating properties, but in essence they are really promoting regulating temperature through moisture management, not active phase change technology.

Were you really in space?
Yes. Outlast® technology was originally developed for NASA for use in gloves and other apparel applications such as pants and socks to buffer and moderate the temperature found in space and very high altitude. In 2005, Outlast® technology was inducted into the Space Technology Hall of Fame for successfully transforming technology originally developed for space exploration into products that help improve the quality of life here on Earth.
