A heavenly ball of wool! Our ALPACA SOXX 4-ply is made up of 70% superfine alpaca and 30% durable nylon. Also, the production process for this yarn is very eco-friendly and it is machine washable on a wool programme up to 40 degrees. Easywash is an enzyme treatment for alpaca fibres, which completely dispenses with any need for environmentally harmful chemicals. Easywash is certified by Ökotex, Bluesign and Reach.
