Introducing:
New ULTRA Merino 120 LT
The all-new 120 LT Series answers KUIU’s never-ending challenge of reducing weight, while improving durability. Now available in Hoodie, Long Sleeve, Short Sleeve, and Zip-off Bottom styles.

ULTRA MERINO
As good as traditional merino wool was, Nuyarn® Merino is better. Conventional ring-spun and core-spun yarns twist the wool fibers into a rope-like structure, which restricts the natural performance benefits. With Nuyarn technology, the wool fibers are drafted over a high-strength nylon filament. You get the benefits of 100% Merino next to skin, with faster dry time, more stretch, tougher seams, added loft, and improved thermoregulation.
