Merino wool is a type of sheep's wool prized for its softness, fine texture, and lightweight warmth. It is considered to be among the finest and softest of wools. It has been used for thousands of years to create the finest garments for people and is still the most popular yarn for knitting.
Merino wool is less irritating than other "coarse" wool fibres. Merino is considered an excellent choice for people with sensitive skin or allergies. Merino is medium-weight wool, with many of the same characteristics as other types of wool, but it is finer, silkier, softer, and more lightweight.
