When you’re looking for something truly special, Luxe Sock Yarn is our decadent favorite for socks. The secret lies in the micron: ‘micron’ is a measurement used to describe the diameter of wool, the lower the micron, the softer + finer the wool. All Merino wool is 24 microns or lower – Luxe Sock Yarn is 19 microns. 90% exquisite 19-micron superwash Merino wool + 10% nylon for stretch and durability, this is the sock yarn your toesies have been asking for. Excellent stitch definition.
