Not too Hot, Not too Cold™
Outlast® fabric was specifically designed to manage heat buildup in astronaut space suits. By using this fabric in a mattress pad, this pad can help to reduce sleep disturbances caused by variations in your body temperature. The Outlast® material works by constantly adapting to these changes, and adjusting to either release or store heat to more effectively regulate your body temperature. The pad itself is approximately 1 inch thick and has a polyester fiber filling under a lining of Outlast® coated fabric and is covered with a 300 thread count 100% cotton top.

Space industry technology for better sleep
Originally developed in partnership with the space industry for application in astronaut space suits, the amazing thermally adaptive; phase changing material used in this cover provides a level of comfort no other material can match. Inside the cover are microcapsules called Thermocules™ specifically developed for their ability to absorb and release stored body heat to maintain balanced temperature. Since the Thermocules™ in the fabric regulates body temperature; it ensures you stay at an optimal temperature for ideal sleeping.

Tested in space and on earth
Outlast® technology is the only phase change material that carries the Certified Space Technology™ seal of approval. The technology was first developed for use by the space industry, and continues to be developed and tested for efficacy and safety, across multiple applications, for major brands around the world. Outlast® currently holds over 96 patents related to thermally adaptive materials.
