For thousands of years, cavemen hunted fearsome creatures like the woolly rhino – scavenging hides to create insulation from the cold. But hides are smelly, flea infested and none too fashionable. So we proudly present the Woolly Rhino Brimmed Cap. Built for beastly cold, it's tightly knit boiled wool for incredible warmth and itch-free comfort. Blended with polyester to give you a scalp-hugging fit that holds in body heat. A glare-blocking "horn" (otherwise known as a brim) keeps you squint-free as you traverse a highly reflective snowfield or drive into the midnight sun.
