Wool

Wool is a natural, protein-based fiber from animals like sheep, goats, and camels, prized for its warmth, durability, elasticity, and natural moisture-wicking/insulating properties, used in everything from cozy sweaters to fine suits. Made from keratin, it's highly versatile, creating various textures from fluffy flannel to smooth worsted fabrics, and is known for temperature regulation, keeping you warm in winter and cool in summer by absorbing moisture without feeling damp.
