This piece in detail ＋

Good to know

  • The comfort of organic cotton flannel, with the look of tailored trousers.
  • The pleat at the waist gives room at the hips: you can sit for hours without feeling squeezed.
  • Pre-washed, the flannel is soft from day one.

Fabric & feel

Flannel is a woven cotton that's lightly brushed: the surface is soft, fuzzy and warm to the touch. It holds in your body heat without getting stuffy. The fabric has body, so the leg hangs well instead of clinging to your thighs. Wash after wash, the cotton gets even softer.

When to wear it?

From the first chilly autumn mornings to the end of winter, when lightweight canvas trousers are no longer enough. For long days sitting at your desk, and smart enough for a meeting or a dinner.

Fit & size

The slightly flared leg leaves room for your calves: you can take long strides without the fabric catching.

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

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.

The cut is made for women, that's rare these days! That's why I've bought these trousers several times. They're soft, understated and go with everything.
