This is the pajama top that blends the cooling properties of a performance fabric with the silky feel of fine lingerie. Using a proprietary technology developed by the company that designs NASA space suits, the hydrophilic fabric wicks moisture away from the skin so it quickly evaporates, preventing the discomfort of overheating or of waking up in a cold sweat. In addition, microscopic silver particles embedded in the open weave material naturally neutralize odor-causing bacteria, so you wake up feeling fresh and well-rested. The 100% polyester pajama top is stain- and wrinkle-resistant, and its cooling and antimicrobial properties last for more than 100 launderings. Machine wash and hang dry. Made in the U.S. White. Women’s size Small.
