Neoprene foam, also known as Monarch, is a soft, flexible, and durable form-fitting sponge rubber that provides good thermal and moisture insulation. It is resistant to ozone, sunlight, oxidation, and many chemicals and petroleum derivatives. Neoprene will also resist breakdown by water and air by virtue of its unique molecular structure. Practical applications of neoprene foam include athletic equipment like gloves, knee pads, and elbow pads
