Unknown Runner uses Nuyarn spinning technology for new apparel line
Arizona-based apparel brand Unknown Runner has integrated Nuyarn’s wool spinning technology into its new Courser Collection, designed specifically for trail runners. The line features tees and tanks made from open knit fabrics to accommodate varied or hot conditions. These garments utilize ultra lightweight fabrics weighing 115 grams per square meter, composed of 63 percent merino wool, 8 percent nylon, and 29 percent polyester.
Nuyarn employs a core spun system that drafts fibers along a nylon filament. According to the company, this twist-free approach avoids the issues associated with conventional ring spinning, which Nuyarn claims can reduce or ruin the natural performance properties of wool, such as moisture absorption.
The technology creates a two-ply yarn with more volume than ring spinning. Monica Ebert, Nuyarn’s vice president of sales, stated that the technology is intended to unlock the natural potential of wool. In high-intensity sports, she said the benefits include durability that is eight times greater and dry times that are five times faster.
Further technical data from Nuyarn indicates that this manufacturing method can improve thermal retention by 35 percent over conventional yarns and produce wool up to 8.8 times more durable than ring-spun versions. The process also offers environmental advantages, reducing energy consumption by 73 percent and raw material use by 30 percent.
Unknown Runner is not the only brand utilizing these advancements. Ugg has used Nuyarn technology for the wool jersey lining of its Otzo clog, which debuted earlier this year. For that specific product, Ugg uses fibers certified by the Responsible Wool Standard. Nuyarn has also collaborated with other brands on products including socks, backpacks, and shoes, as well as the Nautilus Fisherman Sweater for Ibex Outdoor Clothing, which combines yarn innovation with 3D-knit construction.
Beyond performance apparel, Nuyarn is applying its patented spinning technology to support the strong wool industry, particularly in New Zealand. The company's Herculan product converts carpet-grade strong wool into a fine yarn. Andy Wynne, CEO of Nuyarn, stated that Herculan proves abundant natural fiber can work in markets beyond traditional confines, allowing strong wool to replace synthetic polyamides in high-impact areas.
This shift comes as the New Zealand wool sector faces pressures from synthetic alternatives. Recent debates regarding Kāinga Ora's decision to prioritize synthetic carpets over wool in public housing have highlighted the precarious position of farmers dealing with declining prices and demand for strong wool.
By enabling strong wool to move into the apparel world, Nuyarn aims to provide new revenue streams for farmers while maintaining the biodegradability, resilience, and breathability of natural wool.
