The Big Hat is a knitted lambswool beanie designed to keep you warm through cold-weather adventures and everyday commutes alike. Crafted from fine 19.5µm lambswool sourced from Australia, it provides exceptional warmth and breathability, and retains its insulating properties even when damp. Houdini keeps natural and synthetic fibers separate to ensure the hat remains fully recyclable and biodegradable — when it reaches the end of its life, it can be returned for recycling.
