Absolutely love the high rise design… I often have 4+ days of spotting following 3 days of normal bleeding so these have given me my freedom back.
The fabric is so soft & comfortable, the high waistband is supportive & the fit of these is just fantastic… so happy to not only have a high waisted option, but for them to be so comfy too!
Love love love will be buying more. Im a size 12 and bought a medium and they are perfect, firm but not too tight. Quite nice tummy control.
Such good quality! I want to throw away all my old undies and replace with all Aunt Flo! Love them

Because period undies are a sanitary product, we can't take exchanges. That's exactly why the 30-Day Risk-Free Trial exists: try your first pair, and if the fit isn't right we'll refund it. Check the size guide before you order; if you're between sizes, size up.
Yes. They replace pads and liners completely on matching flow days. On heavier days, plenty of women pair them with a tampon or cup as backup.
Yes. Our undies are PFA free and made with OEKO-TEX certified fabrics.
As a guide: on light days one pair comfortably lasts up to 8 hours. On moderate to heavy days, change more often, the same way you would with any period product.
