This piece in detail +

Good to know

  • A knit with body: the jumper holds its own shape and doesn't hang like a limp knit.
  • A big roll neck that comes high up the neck and keeps the warmth where you lose it fastest.
  • Knitted, dyed and made in Portugal, in GOTS-certified organic cotton.

Material & feel

Organic cotton in a chunky rib, soft to the touch with a weight you feel on your shoulders. The tight construction gives real thickness, with no wool or added fibre. If it relaxes after a few wears, it regains its shape in the wash.

When to wear it?

From October to March, as your main piece on cold days or under a roomy coat. Handy at the office or at home when the heating is low.

Fit & size

On the short side, it doesn't bunch at the waist when you sit down. Enough room in the arms to move without the chunky knit 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.

We validate

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

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…

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.

★★★★★ ★★★★★ Size S · Navy blue

Really nice jumper and really nice colour. I bought it in green size M last year and I'm so happy with it that this year I bought it in blue, but I took S because it runs large in my opinion.
