This piece in detail +

Good to know

  • Close to the body without squeezing: the rib follows every move and springs back into place.
  • An organic cotton knit that feels nice against your skin all day long.
  • Arms free and neck covered: a neat look that lets you move without anything pulling.

Material & feel

An organic cotton rib: fine vertical ribs that give the knit some stretch and a soft feel. The compromise: 5 % elastane. It helps the rib get its shape back through the day and lets the top fit more body shapes.

When to wear it?

From May to September, on its own, at the office or at the weekend. The rest of the year, as a base layer under a warmer piece: thin and close-fitting, it doesn't add bulk at the arms.

Runs slightly small. If you're often between two sizes, take the larger one.

Care guide
