This piece in detail +

Good to know

  • A 100% organic cotton flannel, brushed to feel soft from the very first wear.
  • The vertical stripes lengthen your silhouette and balance the volume of the fit.
  • Structured enough to look smart, soft enough to wear open as an overshirt.

Material & feel

Flannel is a woven cotton that's brushed on the surface: it feels fluffy and warmer than a classic shirt. The brushing traps a little air, so it keeps you warm without weighing you down. And with 100% organic cotton, nothing added, it stays comfortable from morning to night.

When to wear it?

From the first chilly days of October, buttoned up and worn on its own. In March and April, open as a light overshirt. In winter, under a coat, it adds a warm layer without any bulk.

Fit & size

The dropped shoulders give room across the back: raise your arms, drive, grab a bag, and nothing pulls. The roominess lets you wear a thin layer underneath.

We recommend you 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.

We validate

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

★★★★★ ★★★★★ Size S · Brown

This shirt is a gem: soft, modern cut and drape, rich and very flattering colour. Looks great with raw denim jeans, corduroy... I went a size down (S rather than M for 1 m 62).
