Wool is a versatile natural fiber that provides insulation through trapped air pockets. Different types of wool come from sheep, alpacas, goats, rabbits, and camels. Sheep's wool varieties include merino, lamb's wool, Shetland, and melton wool. Merino wool is particularly soft and breathable. Alpaca wool is softer than cashmere and lighter than sheep's wool. Mohair from goats is durable and lustrous. Angora wool from rabbits is exceptionally soft and warm. Cashmere from goats is extremely soft and lightweight. Camel hair is also luxurious and warm. Each wool type has distinct properties making it suitable for various clothing and textile applications.
