Collection: Period Underwear

Period underwear turns the hardest days of your month into ordinary ones. These period briefs, a hiphugger and two overnight styles hold your flow and sit smooth under your clothes, so you stop counting bathroom trips. Picture the after: one soft pair instead of a pad, a backup and a spare. No crinkle when you sit, no towel on the sheets. Your period still shows up when it wants; it just doesn't get a vote on your outfit anymore.

Plenty of period underwear asks one pair to do every job. Ours is built for the day you're having. The Sport-Stretch High-Waist Period Brief pairs a stretchy nylon-spandex knit with a high waist that holds its place mid-squat. The High-Waist Organic Cotton Heavy-Flow Period Brief stacks four padded absorbent layers under a top layer that wicks fast, in sizes XS to 6X. The Leakproof Seamless High-Waist Period Brief is bonded, not sewn, so nothing ridges under tight knits.

For nights, the Overnight Leakproof Sleep Short runs its super-absorbent gusset from the front waistband right through to the back, following the route flow takes while you sleep. The Overnight Disposable Leakproof Underwear adds reinforced leak guards, and its sides tear open for a quick change at 3 a.m.

How to choose your period underwear

  • Flow level: for regular days, or as backup for your cup, disc or tampon, the Leakproof Seamless brief. The Soft-Stretch Period Hiphugger stays leakproof for up to 12 hours and controls odor. Heavy days call for the Heavy-Flow or Sport-Stretch brief.
  • Day or overnight: by day, choose by flow. At night, go for full coverage with the sleep short, or disposables when you'd rather toss than wash.
  • Washing and care: after each wear, rinse cold, then machine-wash cold and air-dry. Skip softener, bleach and the dryer; heat breaks down the leakproof layers.

Want shaping too? The Smoothing High-Waist Leakproof Brief lives with our tummy-smoothing shapewear. For workouts, add our supportive sports bras.

Period underwear FAQ

How do period briefs stop leaks?

Absorbent layers in the gusset soak up flow, and a barrier layer beneath them keeps it inside the brief instead of on your clothes. The hiphugger's barrier is a coating of thermoplastic polyurethane.

Can I wear leakproof underwear for bladder leaks?

Yes. The Leakproof Seamless brief handles light bladder leaks, sweat and discharge; the sleep short covers bladder leaks and the postpartum weeks.

How should period underwear fit?

Snug, so the gusset stays in place. The Leakproof Seamless brief runs large, so size down between sizes; the hiphugger and sleep short run true to size. The disposable briefs are sized by waist.
