Like all Manta Yoga Clothes, our Abi Island Skirt is made from Manta--100% all-natural cotton. Unlike the cotton fabric used in conventional cotton clothing, Manta Yoga Clothes are neither mass-produced nor processed with harsh chemicals. And you can really feel the difference! We believe Manta Yoga Clothes are truly the world's most comfortable clothing. Because Manta Yoga Clothes are 100% cotton and pre-shrunk, you can machine wash and dry them without any worries.
