The Rototo Two Stripe Slub Sock Black is made of a mix of two different yarns to create a heather color, dirt and fuzzballs dont stand out on the surface even after repeated use. Knitted with a mix of eco-friendly organic cotton slub yarn and recycled polyester yarn, the fabric provides both the comfort of cotton and the quick-drying properties and durability of polyester.

With help from a spinning mill in Osaka, Rototo created this yarn after repeated trials in selecting the blend and thickness of the yarn as well as the slub width. Each yarn is carefully and slowly spun by skilled operators with an old spinning machine that has been used since the 1950s.
