Bjork MC 140 Women: Fjork Merino's take on the everyday merino tee

What it is

The Bjork MC 140 Women is a T-shirt from Fjork Merino, a brand that designs and develops its technical wool clothing in Switzerland. It’s built entirely from merino wool and sits in that grey zone between base layer and everyday top — the kind of piece you might wear under a shell on a cold hike, or on its own on a mild day in town.

It comes in six colourways, each named after a Swiss (or Swiss-adjacent) resort: Black Laax, Blue St-Moritz, Grey Zinal, Nude Scuol, Pink Davos and Green Engelberg. This is a women’s-specific cut, sold as one style across those six colours.

Who it’s for: anyone who wants a merino T-shirt they can wear close to the skin, whether that’s for a day on the trail, a train journey across cantons, or simply because they prefer wool to synthetic fibres against their skin.

Why it exists

According to the brand, the point of this T-shirt is to offer an ultra-light merino garment that manages temperature and moisture without the synthetic fibres found in most everyday sportswear. Fjork Merino positions itself around durability, animal welfare and responsible materials — the Bjork MC 140 Women is presented as a practical expression of that stance: a T-shirt someone can wear daily, not just for one type of Alpine outing.

The brand also frames this piece as an answer to a common complaint about wool clothing — that it can feel heavy or itchy. The 100% merino composition, combined with flat, anti-irritation seams, is the brand’s response to that concern.

What matters

Composition — 100% merino wool. There’s no blend here, no added synthetic fibre for stretch or durability. That matters because the T-shirt’s performance — how it breathes, how it feels against skin, how it manages odour — comes entirely from the wool itself, for better and for worse. A pure wool garment tends to feel different from a wool-synthetic blend: softer in some ways, less elastic in others.

Wool origin — Australia. The raw material comes from Australian merino sheep, a common source for technical wool garments. This detail matters for anyone tracing where their clothing comes from, and it sets up the next point.

Non-mulesed certification, verified by AWTA. The wool is certified non-mulesed, meaning it comes from sheep that haven’t undergone the mulesing procedure, and this claim is checked by AWTA. For buyers who care about animal welfare in wool sourcing — which Fjork Merino says is central to its values — this certification is the concrete proof behind that promise, rather than just a marketing line.

Flat, anti-irritation seams. Flat seams sit closer to the body than standard seams and reduce rubbing, which matters most where a T-shirt meets skin repeatedly — under a backpack strap, for instance, or against a lower back over hours of movement. This is a construction detail rather than a fabric one, but it directly affects comfort over a full day of wear.

Raglan sleeves. The raglan cut runs the sleeve seam diagonally to the collar rather than around the shoulder. This typically allows a wider range of motion in the shoulders and arms, which is relevant if the T-shirt is worn during activity rather than just at rest.

Dropped hem, front and back. A hem that sits lower at front and back than at the sides is designed to stay tucked in or covered during movement — bending, reaching, sitting down — rather than riding up.

Day to day

As a 100% merino wool garment, it generally asks for gentler handling than synthetic sportswear.

In terms of how it’s worn, the flat seams and raglan sleeves point to a garment designed to move with the body rather than sit rigidly on it, and the dropped hem suggests it’s meant to stay put during activity rather than only when standing still.

What the brand says

Fjork Merino describes the Bjork MC 140 Women as ultra-light thanks to its pure merino composition. The brand states that merino wool provides natural thermoregulation and effective moisture management, and that the fibre’s antibacterial properties give the garment natural resistance to odour.

On sourcing, Fjork Merino states that its non-mulesed wool guarantees animal welfare, and more broadly, the brand says it places sustainability and ethics at the centre of its values. These are the brand’s own statements about the product and its approach.
