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 210 is a mid-weight layer with the perfect balance of warmth, comfort, and durability, remaining effective in a range of conditions, even when worn for days on end. Itch-free, moisture wicking, and naturally odor resistant, the premium Merino wool takes the edge off in cold weather, while the full length leg zippers allow you to easily shed layers in changing weather conditions. The distinctive construction of the 210 maintains the natural benefits of wool, while providing a soft, brushed polyester fleece against the skin to eliminate itch. The unique design of the zip-off bottom allows easy on and off without having to take off your boots or pants. Wear as a base layer or layered over our other ULTRA Merino collections in colder conditions.

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.
