Key Benefits

  • Twice as soft as cotton.
  • Wicks moisture for up to 10 hours.
  • Breathable and antimicrobial gusset.
  • Designed for shape and flexibility.


The Everyday Brief - Black blends soft-touch comfort with technical performance. Made from TENCEL™ Modal, a natural fabric derived from cellulose, it offers twice the softness of cotton and a barely-there feel. This high-performing fabric is breathable and helps wick away moisture for up to 10 hours, keeping the skin dry and irritation-free throughout the day.

The extended bamboo gusset features antimicrobial properties, helping maintain freshness and supporting intimate skin health. With an adjustable rise and cross-over waistband, the fit flatters every body shape while retaining its form wash after wash. Its adaptable stretch makes it suitable for pregnancy and postpartum wear, offering all-day ease without compromising support. The Everyday Brief - Sand is OEKO-TEX® certified, ensuring it’s free from harmful substances and safe for sensitive skin.

Why Underdays is Healf
Underdays uses breathable fabrics that feel soft against the skin and adapt to your every move. Each piece carries the OEKO-TEX® certification, meaning it has been tested for harmful substances and proven safe for direct contact with your body. The fabrics offer all-day comfort without irritation, making them ideal for both busy routines and moments of rest.

Underdays was founded in December 2021 by Oria Mackenzie & Amelie Salas with a mission to reimagine underwear as a form of everyday self-care. Inspired by the idea that underwear should feel as good as it looks, the founders set out to create pieces that combine style, comfort, and performance. Each design is developed in collaboration with a gynaecologist to support women through daily routines, active moments, and everything in between. By focusing on breathable fabrics and thoughtful fits, Underdays empowers you to feel confident, supported, and comfortable every single day.
