95% TENCEL™ Modal, and 5% Elastane


Fits true to size

We use sustainable materials and dyeing processes, because you wouldn't want toxic chemicals in your undies, would you?

Our Bikini Brief is sustainably made from a super-soft and durable blend of 95% TENCEL™ Modal, and 5% Elastane.

Why TENCEL™ Modal?

It's pretty simple: it's softer, more comfortable and more sustainable. In real terms, that means:

  • 3x softer than cotton
  • Shrink-resistant
  • 50% more absorbent than cotton + moisture wicking properties = fresher undies for longer
  • 50% more breathable than cotton
  • Holds its own shape, so it clings to yours for longer
  • Antimicrobial and hypoallergenic

    Usually our undies fit true to size.

    Looking after your undies isn't rocket science. So long as you use a cool wash and low dry cycle, they'll love you back.

    • Wash cool, dry low
    • Don't iron, bleach, or dry clean
    • For best performance: hand wash cold and lay flat to dry
