What Is Nuyarn? The Merino Wool Upgrade Every Hiker Should Know About
Nuyarn is changing the way we think about merino wool. With more strength, breathability, and comfort than traditional fabrics, it’s becoming a go-to for hikers and backpackers who want gear that performs on every mile of the trail.

When you’re out on the trail, the clothes you wear aren’t just about comfort—they’re gear. They need to keep up with the miles, handle shifting weather, and last through seasons of adventure. That’s why I’ve been excited about Nuyarn, a new way of spinning merino wool that’s changing the outdoor gear world.
Merino is already a favorite for hikers and backpackers because it naturally regulates temperature, resists odor, and feels good next to the skin. But Nuyarn takes all of that and turns the dial up.
What Exactly Is Nuyarn?
Traditional merino fabrics are made by twisting wool fibers together. Nuyarn does things differently. It uses a draft-free spinning process that keeps fibers more aligned and natural instead of squeezing the life out of them with a tight twist.
The result is merino that’s:
- Stronger (up to 35% stronger than ring-spun)
- Warmer for the weight with more loft and insulation
- Faster drying and more breathable
- More durable, resisting pilling and wear
- Softer and more flexible against your skin
It’s basically everything we already love about merino, but made to handle more trail time with less compromise.
Why Hikers and Backpackers Love It
When you’re living out of a pack, every ounce and every layer matters. Here’s why Nuyarn makes a difference:
All-Season Comfort
Hot days, cold nights, Nuyarn adjusts with you. It traps warmth when you need it and breathes when you’re working hard.
Quick Drying & Sweat Control
Nuyarn wicks moisture five times faster than traditional merino. That means you’ll spend less time in a damp shirt on climbs or humid hikes.
Built Tough for the Backcountry
From backpack straps rubbing to bushwhacking through scrub, Nuyarn fabrics stand up to the abuse. They last longer and pill less, which means you’re not replacing gear as often.
Ultralight Packability
Nuyarn offers more warmth without the weight. Perfect for keeping your kit light while still being prepared.
Earth-Friendly Performance
Merino is renewable and biodegradable. Nuyarn makes it last longer, which means less waste and more sustainable choices for the backcountry.

Is Nuyarn Worth It?
If you’re serious about gear that performs, the answer is yes. Nuyarn is built for hikers, backpackers, and anyone who pushes their layers hard in wild places. It feels better, lasts longer, and keeps you more comfortable through it all.
For me, it’s the kind of upgrade that just makes sense—once you try Nuyarn, it’s tough to go back to regular merino.
Packing It Out
Gear is meant to support the journey, not hold you back. Nuyarn’s innovation gives us fabric that works with the rhythms of the trail: lighter, stronger, and more breathable without losing the natural magic of merino.
If you’ve been curious about upgrading your kit, adding a Nuyarn piece is a great place to start.
