The Big Hat is a classic-fit knit beanie crafted from 19.5 micron lambswool, offering reliable warmth that holds even in wet conditions. Made from 100% pure lambswool sourced from mulesing-free farms in Australia and knitted in Sweden, it meets both GOTS and ÖKO-TEX 100 standards. Houdini keeps natural and synthetic fibers separate to ensure the hat remains fully recyclable and biodegradable — when it reaches end of life, it can be returned for material recovery.
