Product Overview

Moisture-wicking when it’s hot, insulating when it’s cold

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 145 is a lightweight, incredibly comfortable, and durable blend of wool and nylon providing a next to skin or layering option for the highly active hunter. Itch-free, moisture wicking, and naturally odor resistant, the ultra fine 17.5 micron Merino wool takes the edge off in cool conditions, while eyelet knit side panels provide maximum breathability. The ½ Zip design adds heat release and ventilation capabilities while the stand collar adds to its comfort and concealment. The 145 is an ideal choice for hunters needing a long term, effective solution in a wide range of aerobic conditions and temperatures.

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.
