Seawool® yarn is made and formed from crushed oyster shells mixed with recycled PET pellets. The oysters used in Seawool® are sourced from either sustainable oyster farms or from the food industry. There are currently four million tons of disused oyster shells worldwide; although they are biodegradable, they do not degrade quickly, meaning that they take up significant space if not upcycled in some way. The finely pulverized oyster shells contribute to the fabric's wool-like texture, offering moisture-wicking, antimicrobial, anti-static properties, and effective heat regulation.
