Organic Cotton fibers are one of the absorbent fibers in nature being able to absorb up to 1/5 of its weight before the cotton feels damp. The structure of organic cotton fiber provides ventilation that allows the cotton to breath. Cotton is a flat and twisted fiber that can be manufactured into a much more elastic cloth than can linen. This structure allows cotton to absorb moisture from the body and quickly dissipate it to the surrounding air, helping to stay cool and dry throughout the night. This inherent air circulation system helps remove body moisture by absorption and regulate body temperature. This is important during sleep, as the skin is constantly releasing moisture while you sleep. Keeping your body temperature regulated during sleep is key to a better night's sleep. The wicking property and quick drying of cotton make it an ideal fiber from mattresses and bedding.
