This piece in detail +

Good to know

  • You slip them on in one go and the waistband follows your body, standing or sitting, with nothing tight around your stomach.
  • A thick fabric that falls straight and looks smart, with the comfort of loungewear.
  • More than half recycled fibres, combined with organic cotton and certified wool.

Material & feel

The fabric is REFIBRA, thick and supple. The wool adds warmth and the organic cotton keeps it soft against your skin. The trade-off: 3% elastane. It helps the waistband and knees spring back and lets the trousers suit more body shapes.

When to wear it?

When the thermometer drops to around 5 to 15 °C and you want to stay warm without tights underneath. Long train or plane journeys: the soft waist doesn't leave a mark, even after hours sitting down.

Fit & size

The straight leg gives you room: you can sit, cross your legs and climb stairs without the fabric pulling at the knees.

If you're between two sizes, we recommend you take the smaller one.

Our charter & our method

Our method

01

We seek out

We look for brands whose approach actually holds up, not the ones with the best marketing.

02

We analyse

We ask for workshop names, compositions and labels, along with the proof to back them up.

03

We validate

Without proof, a brand doesn't make it into our catalogue. It's the one rule that's non-negotiable.

Our selection charter · 3 pillars

Respect for people

  • All brands share the names of their partner workshops with us.
  • All of them commit to respecting the fundamental principles of the International Labour Organization.

02

Care for the planet

  • 100% of the clothes we select are made from at least 90% organic, vegan, recycled or natural materials.
  • All brands give us proof, with labels and certifications: GOTS, OCS, Oeko-Tex, Bluesign…
03

Integrity and values

  • At least 75% of collections must be eco-friendly.
  • All of them commit to always doing better, never worse just to produce more.
