It features soft, temperature balancing fabric that insulates when you're cold and wicks moisture when you're hot. Recycled, hypoallergenic fiber re-fluffs with each wash for comfort and support. Antimicrobial product protection inhibits the growth of odor-causing bacteria, keeping your pillow fresher between washes.
