Sheep's wool is unique for its lanolin, the soft, waxy substance taken from the wool and used as a softening agent and in ointments.Sheep's wool is also fire-resistent. Unlike cotton and other fibres which burn readily, wool will only smoulder, and not catch fire easily.
Virgin merino wool is an unprocessed wool and is obtained from merino sheep or lambs. Regular merino wool is processed from the withers only of merino sheep. While not as soft as virgin merino wool, the regular merino wool is still of excellent quality.
