Nuyarn® by The Merino Wool Company

Changing the Very Fabric of Yarn

KUIU’s quest for the finest ingredients led us to New Zealand, where they take their wool remarkably seriously. Nuyarn is not a new fabric, it’s a new way of making fabric. 

Classic yarns twist fibers together for strength, which leaves ends poking out. Nuyarn takes the twist out, and instead lays fibers along the same orientation, so fabrics feel less prickly and more comfortable yet become stronger. Nuyarn lower-density fabrics let lighter-weight garments outperform heavier traditional ring spun garments.
