Softies combine patented performance fabric with sheer luxury to create the most comfortable pajamas you will ever wear. Optimer Performance Fibers%u2019 Dri-release® high-performance fabric keeps you cool and dry all night by quickly moving sweat and moisture away from your skin through the fabric, releasing it to the air. Fresh Guard® neutralizes odors and inhibits bacteria growth caused by sweat. Softies require no special care (machine wash and dry), are colorfast and will resist shrinking.
