Dry Fast foam is a durable foam perfect for wet or damp environments such as marine applications or outdoor seating. It does not retain water or moisture and has antimicrobial properties to prevent rot or mold growth. It is also known as Quick Dry, Ever Dry, Easy-Dry, or Calipore foam. With most foams, from even a short distance away, you would barely be able to see any of the tiny cells that make up the structure of conventional polyurethane foam. http://www.siliconepillows.com/pillow/baby-silicone-pillow/
