Wool is a miracle material, known by more names today than ever before. Merino from sheep. Cashmere and mohair from goats. Angora from rabbits. Not to mention those other exotic forms most mortals can’t afford. Its natural fibers retain air, giving it one of the highest warmth-to-weight ratios of any insulator in existence. It can absorb up to 1/3 of its own weight in water and successfully disperse it, keeping wearers dry even in soggy conditions while also resisting bacterial growth and the odors that come with it. It’s hypoallergenic and fire retardant, igniting at a higher temperature than cotton or most synthetics. No wonder we’ve found ways to add it to all manner of things. Behold: the versatility of wool.
