FAQs

Outlast® technology is the original, proactive heat and moisture management technology, and is also the only phase change material that is a Certified Space Technology™. Outlast® fabrics, fibers and coatings are ingredients found in everyday products and high performance gear.



Outlast® technology is proactive, using phase change materials (PCM) to absorb excess heat from your skin when you are warm, and releasing that heat back to you when you need it most. For example, ice is also considered a phase change material and as the ice in your drink changes from solid to liquid, it absorbs heat and cools the drink. The phase change materials in Outlast® technology work in the same way.



Outlast® technology is proactive technology that adapts and changes based on your personal situation. When you get hot, Outlast® technology absorbs heat. When you get cold, that heat is released. Outlast® technology balances your temperature proactively by managing heat to reduce overheating and perspiration.



When Outlast® technology is designed to be part of a fiber, it is a permanent part through the life of the garment. Our coated products also have excellent durability.



Every fabric and fiber is different. Look at the care instructions on the products containing Outlast® technology, they are based on manufacturer recommendations and are specified on the label.



With in-fiber technology, Outlast® technology is spun directly into yarns and fabrics. Outlast® technology can also be coated directly onto fabrics using a padding treatment or knife-over-roll process. Please see the process overview section.



It is different for each product but Outlast® fabrics, coatings and fibers are most effective when they are worn closest to the skin.  For footwear or outerwear Outlast® technology is designed to be used as liner or interliner materials.



Look for the Outlast® logo on the hang tags and labels of products.  Every product must undergo strict testing to carry an Outlast® hang tag and/or label.



Outlast® technology is proactive rather than reactive. Many products claim to regulate temperature, but they actually manage moisture created by the skin. And by the time they start working, you’ve already experienced discomfort from overheating and perspiring. Outlast® phase change materials proactively absorb and store heat to manage heat thus managing moisture and reducing it.



Yes. The Certified Space Technology™ seal is issued by The Space Foundation. Outlast® technology was originally developed for NASA for use in gloves and other accessories to regulate temperatures found in space and very high altitude. Outlast was most recently in space when Japanese Astronaut Naoko Yamazuki wore a sweater made with Outlast® fibers.
