Confidence, every day of the month. These leak-proof bikini briefs pair a soft breathable cotton-spandex jersey exterior with a black technical gusset that extends higher at the back for added security when you're sitting or lying down. The result is a period-proof everyday underwear that looks and feels like your favorite bikini — but works as a reliable backup for tampons, cups, and pads on heavy or light flow days.
Ideal for travel days, overnight, postpartum recovery, and the unpredictable days of your cycle. The flat-seam construction means no visible panty lines under leggings, yoga pants, or fitted dresses, so you can move through your day without a second thought.
The Details
- 3-pack value — charcoal heather, solid grey, and pale blush (one for each phase)
- Extended leak-protection gusset with a black technical interior lining
- Breathable cotton-spandex jersey that stays soft wash after wash
- Flat-seam construction — no visible panty lines under fitted outfits
- Versatile bikini cut with high-cut leg and modern low-rise waist
