Why we picked it
Underwear with the pad built in, holding a couple of tampons' worth before anything needs attention. Rinse after wearing, machine wash cold, hang to dry, and a pair keeps working for years. The gusset construction is where the engineering lives; the rest looks and feels like regular underwear because it mostly is. Worth noting the fabric is a cotton blend with some synthetic content.
What it’s made of
Cotton/nylon blend with leak-proof layer. Chosen for what it’s made of, not what it’s wrapped in.
- Organic cotton
- GOTS-grade fibre that won't shed microplastics in the wash.
- Compostable
- Plant-based and certified to break down, not pile up.
