Extra-Fine, Super-Fine, Ultra-Fine
Fibres are only wool if they come from sheep. So cashmere, alpaca and mohair (which come from goats and alpacas) are actually hair, not wool, and can be coarser and itchier. Some wool fibres can be 25 microns in diameter or more, but here at Giannotti, we use only the very best merino wool fibres: Extra-fine merino which is less than 19.5 microns, super-fine which is less than 18.5 microns, and Ultra-fine which is less than 15 microns.
