Cashmere is a type of wool that comes from goats, specifically the pashmina and cashmere breeds. It gets its name from the Kashmir region of India, where these goats can be found. According to the brand Quince, cashmere is three times as warm as wool and comes in three grades: A, B, and C, with A being the highest quality and most durable. The longer the fibers, the softer they are.
