Fjork Merino: sportswear built from a single fibre, designed in Valais
Based in Sion, Fjork Merino builds its entire sportswear range around certified mulesing-free merino wool, from t-shirts to children's jackets.

Sion, in Valais. That’s where Fjork Merino designs its sportswear, working with a single material that never changes: merino wool, and nothing else. The brand presents itself as independent and states that it uses only certified mulesing-free wool, sourced from farms that respect animal welfare standards. A tight, almost uncompromising positioning that shapes everything else.
A brand rooted in Valais
Fjork Merino hasn’t built its identity on a flashy success story. Its headquarters are in Sion, and this Valais address sets the tone: a Swiss, independent brand that has chosen a single fibre for its sportswear. The name itself evokes fjords, Nordic, mineral imagery that fits well with a wool known for standing up to both cold and effort. The rest of the story is told mainly through the brand’s products and material choices, rather than through a foregrounded founding narrative.
A range built for everyday sport
Fjork Merino’s catalogue is built around technical pieces designed for physical activity, but made to last well beyond a single outing. It includes t-shirts, such as the Bjork MC 140 Women, jackets for younger wearers such as the Ultra 300 Kids, hoodies available in women’s and men’s versions with the Titlis model, as well as further technical pieces still in preparation, from the Finn 210 zip top to Classic Cut socks, plus neck warmers and Strahlorn boxers. The brand is therefore aimed at both athletes and families, with an offering that spans technical tops to everyday accessories, always with merino wool as the common thread.
The know-how: it’s all in the fibre
At Fjork Merino, the technicality doesn’t come from stacking membranes or chemical treatments, but from the fibre itself. The brand states that merino wool can absorb up to 35% of its weight in moisture before feeling wet, which changes how a garment feels during prolonged effort. It also states that this wool responds in real time to body temperature, unlike synthetic fibres, with the idea of a garment that adapts rather than insulating in a static way. Another point put forward by the brand: the keratin in merino wool is said not to retain the molecules responsible for unpleasant odours, unlike polyester. A concrete consequence, according to Fjork Merino: one of its t-shirts could be worn for several consecutive days without washing, without developing an odour. These are claims made by the brand, but they do show where Fjork Merino places its added value: in the raw material more than in the garment’s construction.
What the brand stands for
The commitment stated by Fjork Merino comes down to one simple requirement: certified mulesing-free wool, sourced from farms that respect animal welfare standards. It’s a criterion the brand places at the heart of its presentation, even before discussing technical performance. Added to this is a claim of independence, that of a Swiss brand that doesn’t dilute its identity across a scattered range of materials, but instead builds its entire wardrobe around a single fibre chosen for its natural properties rather than its cost.
Right now
Fjork Merino’s recent activity shows a brand steadily building out its wardrobe. In September 2026, the Bjork MC 140 Women t-shirt joined the range. In late August 2026, two new pieces arrived on the same day: the Ultra 300 Kids jacket, designed for younger wearers, and the Titlis hoodie, available in women’s and men’s versions. A little earlier, in July 2026, the brand opened pre-orders for trade professionals covering several pieces from its autumn-winter collection, including the Finn 210 zip top, Classic Cut socks, a neck warmer and the Strahlorn boxer. Altogether, a range that keeps growing season after season, always around the same material.
For a Swiss reader
Fjork Merino is a fully-fledged Swiss brand, headquartered in Sion, in the canton of Valais. For a reader in Switzerland, this means direct geographical closeness to a brand that designs its products locally rather than having them designed elsewhere.
Why we like it
We like this way of committing to a single material, merino wool, and building an entire family range around it, from the women's t-shirt to the men's hoodie to the children's jacket. We also note the mulesing-free commitment stated plainly, which gives a clear framework for the wool's origin.
Exactly the kind of brand we’d love to come across on O!deal one day.
