Product Overview

Developed in New Zealand, Nuyarn technology has revolutionized the Merino wool market. Taking the twist out of the yarn has produced a fabric with higher stretch and recovery, better moisture management, and greater warmth. It is stronger than the average Merino wool on the market, yet boasts the same natural odor resistance and comfort.

KUIU’s ULTRA Merino socks are designed for high-stress outdoor activity where additional technical support of the feet is required. The style and shape compliments a wide range of footwear while adding protection to your feet. Highly breathable and moisture wicking, this sock molds to your feet, ensuring shear friction is reduced and skin integrity is kept optimal.
