How We Apply Outlast® To Our Products

Our product development team designs each product with one or more of the Outlast® application methods below for the best performance.
Fibers & Yarns

The technology is embedded directly into the fibers, which are spun into yarns and then knitted or woven. Outlast® fiber applications are ideal for products that come in contact with the skin i.e. sheets.
Filling

The technology is embedded directly into the fiber filling for duvets, blankets, or comforters.
Coatings

The technology is applied over the surface of a fabric using a printing coating method. These coated fabrics have the highest capacity to absorb heat and are used in mattress pads, pillows, pillow covers, and more.
