This piece in detail ＋

Good to know

  • 100 % organic cotton certified to the Organic Content Standard, nothing else in the canvas.
  • A clean look despite the volume: the canvas falls straight instead of clinging to your legs.
  • Room at the thighs and knees: you can sit, crouch or cycle without anything pulling.

Fabric & feel

A dense organic cotton canvas that isn't see-through. A little stiff the first few times you wear it: that's what gives the trousers their structure. It then softens and moves with you, without losing its shape.

When to wear it

From September to May, when light trousers aren't enough. On days when you go from walking to cycling to long hours sitting down: the dense canvas keeps out the wind and the roomy leg lets you move.

Runs slightly large. If you're often between two sizes, 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

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.
