Made from ultrasoft, sustainable Seawool yarn. The Seawool Neptune Beanie has a silky, wool-like texture that doesn't itch or irritate your skin. Its innovative Seawool fibers combine crushed oyster shells and recycled plastic bottles for incredible performance. The simple ribbed knit and cuffed design is ideal for everyday wear, but its antimicrobial, anti-static, and insulating properties are exceptional.
