This piece in detail +

Good to know

  • Organic cotton and nothing else: a crisp canvas that holds its shape on its own.
  • Room through the hips and thighs, a clean line at the hem: the volume doesn't bunch up over your shoes.

Fabric & feel

A 100% organic cotton canvas, dense and matt. Firm at first, it then moulds to your body and softens wash after wash. The black stays deep and opaque, with no shine.

When to wear it?

From September to May, for long days that run from commute to meetings to dinner. In summer, better for evenings and mild days: the dense canvas keeps your legs warm.

Fit & size

You can sit, crouch and climb stairs without the fabric pulling at the knees. Narrowed towards the hem, it doesn't drag on the ground or catch in your bike chain.

True to size. Take your usual size.

Our charter & our method

Our method

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.

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.

Review summarybased on 15 reviews

Trousers loved for their exceptional comfort, original and elegant fit, and great durability. A well-made quality basic that wins people over with its careful finishes. Note, though: the fabric can tend to attract dust. An excellent choice!
