What are the differences between the grades of alpaca fleece?
Where applicable, the grade of the alpaca fleece used to make the product is listed with that product’s page. Fleece is graded for its fineness (diameter of the fibre shaft) and is measured in microns (μ) which is a millionth of a metre. The lower the micron number, the finer the fleece. To give you a sense of the fineness of alpaca fleece, human hair averages around 50-75 μ.
