Trail running is one of the places Nuyarn® does its best work, and this September it caught the attention of Textile World, which named the Nuyarn® x Unknown Runner fabric its Quality Fabric of the Month. The feature puts the spotlight on the ultralight merino behind Unknown Runner’s debut Courser Collection. Here’s a closer look at the collaboration, what makes the yarn work so well on the trail, and why more running brands are choosing Nuyarn®.
The Courser Collection
Unknown Runner, founded by trail-running partners in Flagstaff, Arizona, designs merino apparel for long days on the trail. Its debut Courser Collection is an ultralight range made for hot, variable conditions.
At 115gsm, the fabric is very lightweight, and it regulates temperature, moves moisture, resists odour and doesn’t cling when you’re working hard.
“We’re always searching for the highest-performing merino fabrics, and Nuyarn’s ability to innovate around performance made them the ideal partner for Unknown Runner”
Alex Mette, Founder of Unknown Runner.

Why Nuyarn® works on the trail
The difference starts in the technology. Conventional spinning twists wool fibres tightly together, limiting how well the wool can perform. Nuyarn® takes a different approach, its twist-free process draws merino around a nylon filament. The result is a yarn that is lighter, handles moisture better and lasts longer than conventional ring-spun wool.
Light where it counts
On a long climb, every gram and every bit of trapped heat adds up. Nuyarn® fabrics have been made as light as 95 gsm, giving runners a garment that feels like almost nothing and breathes easily when the pace picks up.
Dries up to 5x faster
Nuyarn® dries up to 5x faster than conventional ring-spun merino, wicking moisture away from the body early. This helps regulate temperature when conditions change.
Made for repeated hard use
Trail gear takes constant abrasion from packs, vests and repeated washing. Nuyarn® is up to 8.8x more durable than traditionally spun merino, so pieces keep performing over many seasons.
Naturally fresh
Merino’s built-in odour resistance means you can wear a piece more than once between washes, which is handy on multi-day adventures.
A growing category for Nuyarn®
Runners increasingly want natural fibres that don’t compromise on technical performance, and brands are looking for options beyond fully synthetic fabrics. Trail running suits Nuyarn® well because the sport rewards exactly what the yarn does: low weight, quick drying and durability.
