Cotton Flex is a type of fabric that is made from a blend of cotton and synthetic fibers such as spandex, elastane, or polyester. It is known for its flexibility, stretchiness, and durability. Cotton Flex is commonly used in the production of clothing items such as pants, leggings, shorts, and sportswear. The addition of synthetic fibers to cotton in this fabric enhances its stretch and recovery properties, making them suitable for a wide range of body movements.
