This piece in detail +

Good to know

  • 100% GOTS-certified organic cotton, nothing added: only a natural fibre touches your skin.
  • Opaque enough to wear on its own, without anything showing through.
  • PETA vegan certified: no animal-derived materials used in its making.

Fabric & feel

Organic cotton is soft from the first wear and absorbs sweat: the tee stays comfortable from morning to night. Wash it inside out at 30 °C to protect the fibre and colour wash after wash.

When to wear it?

From the first warm days of May to the mild evenings of September, on its own. The rest of the year, as a base layer in an overheated office: cotton absorbs what a synthetic would trap against your skin.

We strongly recommend you take one size up from your usual size. This piece runs small.

Our charter & our method

Our method

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.

Review summarybased on 49 reviews

Soft, eco-friendly and well cut, this t-shirt is loved for its quality and comfort. While some find the fit long or the fabric thin, most highlight how well it holds up in the wash and its neat finishing. A durable basic at a fair price.

Colour a bit dull in the end, but I kept it anyway. Usually a quality brand, I bought it recently... We'll see how it wears.
