Size Guide

Find your fit.

Two sizes. Same soft medical-grade silicone. The right one depends on your flow and body — most people start with S.

S 20 ml

Light to medium flow


  • Under 30
  • No vaginal birth
  • C-section only
  • Light–medium flow
  • Smaller or average build

≈ Holds equivalent to 2–3 tampons

L 25 ml

Medium to heavy flow


  • 30 or older
  • Post vaginal birth
  • Heavy flow
  • Larger build
  • Longer wear between empties

≈ Holds equivalent to 3–4 tampons

Not sure? Start with S — it fits most people. You can always size up next cycle. Both sizes come with the same ergonomic ring and 90-day guarantee.
