This piece in detail +

Good to know

  • An elasticated drawstring waist: you set the hold yourself, no belt needed, and stay comfortable even sitting for hours.
  • A real zip fly, well hidden: the look of smart trousers with the comfort of loungewear.
  • They stop at the ankle: the hem doesn't drag on the ground or wear out under your heel.

Material & feel

An organic cotton canvas, nothing added. Firm for the first few days, it shapes to your body as you wear it. Dense with good coverage, it keeps a sharp look, far from the pyjama effect.

When to wear them?

All year round, except in a heatwave. Made for long train or plane journeys, relaxed office days and busy weekends.

Fit & size

The straight leg leaves room at the knees: you can sit, climb stairs and crouch without any pulling.

We recommend you take your usual size.

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

01

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.
  • When they manufacture in high-risk countries, we ask for additional guarantees and labels.
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.
