Jockey® staycool incorporates an Outlast® technology treatment that uses phase change materials (PCMs) that absorb, store and release excess heat to maintain optimal external body temperature. The treatment is printed onto the fabric, creating an invisible microclimate of comfort between the garment and your skin by regulating temperature. Jockey is the first company to market both women's and men's underwear treated with Outlast® technology to the U.S. market, which was originally developed for NASA to help balance temperature fluctuations in space.

The Jockey® staycool line is available in multiple colors with a suggested retail price of $21 for women's tops, 2/$27 for men's, and 3/$24-$29.50 for underwear.

Jockey® staycool is available at Jockey.com, 1-800-JOCKEY1, Jockey-branded retail stores and various fine retailers across the U.S. and Canada.
