The ULTRA Merino 120 LT answers KUIU’s never-ending challenge of reducing weight, while improving durability. KUIU partnered with Nuyarn® to engineer merino wool sourced from New Zealand that was lighter than the 125 g/m² predecessor, yet stronger. Merino wool as a natural fiber excels at thermoregulation and odor resistance, which are critical for long-duration hunts. Without sacrificing performance or comfort of the natural softness from the 17.5-micron fiber, the new 120 g/m² fabric uses a thicker nylon yarn core through Nuyarn technology, creating higher dimensional stability, improved regain, and added durability. The result is the lightest and toughest in the industry.

This base-layer top is sized with an athletic next-to-skin fit. It's streamlined to comfortably fit the same size mid and outer layers over the top. Only upsize if you measure between sizes or prefer a loose fit.
