This piece in detail ＋

Good to know

  • Pure organic linen, with no cotton or synthetics blended in: all the freshness of linen, nothing else.
  • Air around the body: the shirt doesn't stick to your back when it's hot.
  • Buttoned cuffs you can undo and roll up your forearm in seconds.

Material & feel

Linen is a fibre taken from the stem of the plant: this fabric is cool to the touch and lets heat escape well. It softens wash after wash and gains character over time. A GOTS-certified linen, organically grown.

When to wear it?

From May to September, as soon as the thermometer goes above 20 °C. At the office on hot days, at the weekend, on holiday when you want to stay covered in the sun.

Fit & size

You can raise your arms, grab your bag or sit down without the shirt pulling at the buttons.

Runs large. Take one size down from your usual size.

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.

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

Care for the planet
