Timeless material. Always evolving.

Wool has been used for generations, but that doesn’t mean we stop pushing the material forward. At Devold, we keep innovating by working with ambassadors like Simen Holvik and Jørgine “Funkygine” Vasstrand, who test our gear under extreme conditions – from desert ultramarathons to arctic dog sled races.

“We’re constantly getting feedback from people who put our gear to the test. We adjust fit and details where it matters,” says Valseth.

But one thing doesn’t change: the material itself. Wool keeps passing the test – again and again. 

When nature gets it right

There are plenty of synthetic options out there promising next-level performance. But when it matters, more and more people are turning back to what’s worked for centuries.

Wool is proof that sometimes, nature still has the best solution.

So next time you suit up – whether it’s for peak summer heat or freezing winter – know this: merino wool performs. It’s been tested in deserts, on mountaintops, at sea. And it delivers.

Nature wins. Every time.

For thousands of years, when people needed clothing they could truly rely on, they chose wool. From Bedouins covering up under a scorching desert sun, to fishermen battling rough seas in hand-knit wool sweaters. Even today, in a world filled with high-tech gear and synthetic super-materials, we keep coming back to what nature perfected long ago.

Ultrarunner Simen Holvik knows this firsthand. When he lined up at the start of the legendary Badwater 135 – one of the world’s toughest ultramarathons, across California’s Death Valley in temperatures reaching 122°F – he chose to run in merino wool. Not because it’s tradition. But because it works.

“Merino wool regulates temperature. It keeps you warm when it’s cold and cools you when it’s hot. That’s a property built right into the fiber,” says Ronny Valseth, senior product developer at Devold.

Nature’s built-in climate system

Unlike synthetic materials, which often need built-in mesh panels or engineered ventilation zones, merino wool is a natural climate system. The fibers have tiny air pockets that insulate while also transporting moisture away from the body and allowing your skin to breathe. The result? A more stable body temperature, whether you're running in the desert or hiking in the snow.

Nature’s technology

While synthetic fabrics keep promising better moisture control and breathability, wool already has it naturally. Merino wool doesn’t need chemicals to perform. Its natural lanolin content helps prevent bacterial growth, which means wool stays fresh longer and doesn’t trap odors the way synthetic fabrics often do. That means less washing and longer-lasting gear.

“I still use the merino shirt I wore at Badwater. I haven’t even washed it. Just aired it out. Still smells fine,” Simen says.

And that’s not just good for comfort – it’s good for the planet. Less washing means less water and energy used. And it extends the life of your gear. Good for your wallet. Great for the environment.
