Wore them to work and then straight to dinner. Not once did I worry about leaks or feel uncomfortable. That never happens on my period.

The absorbent layers are built right in, so they feel just like regular underwear without the bulk of a pad. I've washed them twice already, and they're still just as soft and comfortable.

Sofie L.

Ordered the black pair after trying the peach. They look just like regular underwear, and the built-in protection means I can finally skip the pads.

Find your size

Four sizes, one comfortable fit. These high-waist briefs come in M, L, XL and 2XL. They’re designed to sit snugly so the leak-protection gusset stays in place, with a soft waistband that holds without squeezing. Choose your usual underwear size. Between sizes? Size up for a little more comfort. Unopened pairs can be returned within 30 days of delivery.

Fabric & care

Made for comfort, built to last. A soft, stretchy fabric moves with you, and the cotton-lined gusset adds a breathable layer where it counts. Rinse in cold water after wearing, then machine wash cold on a gentle cycle or wash by hand. Don’t use bleach or fabric softener, because softener reduces absorbency. Line dry, and don’t tumble dry or iron.

Shipping & returns

Free shipping on orders over $50, with tracking. Orders are processed within 1 to 5 business days, then arrive in 7 to 12 business days in the US, Canada and the UK, or 10 to 20 business days in Australia and New Zealand. Ordered the wrong size or colour? Unopened pairs can be returned within 30 days of delivery. If we sent the wrong item, or it arrived damaged, contact us within 7 days and we’ll replace or refund it for free.

Thoughtful period protection

Designed to protect

Most period products can feel bulky, uncomfortable, or visible
under clothing. Our period underwear is made to feel like regular
underwear while giving you the leak protection you need
throughout the day.

The absorbent layers are built right in, so you get softness,
security, and confidence in one simple essential.

Built-in absorbent layers for reliable leak protection

Soft, breathable fabric for everyday comfort

Washable and reusable for period care that lasts

One dress, every hour

Start the day secure

The high waistband sits soft and flat under jeans, leggings or a work outfit. The lengthened gusset covers front to back, so you don’t have to think about it on the way out the door.

Moves with your plans

Soft, stretchy fabric moves with you through work, errands and a long day on your feet. The cotton-lined gusset stays breathable, so you feel fresh hours later.

Rest easy

The extended gusset runs all the way back, adding coverage while you sleep. On heavier nights, pair them with a pad, tampon or cup for backup protection.

The period underwear you’ll actually reach for

Period underwear should feel like underwear, not like a compromise. These high-waist briefs pair a soft, stretchy fabric with a lengthened, widened gusset that runs from front to back, so you stay covered from morning to night. Wear them on their own on light to moderate days, or as backup with a pad, tampon or cup on heavier ones.

  • Extended leak protection, front to back.
  • Cotton-lined gusset, soft and breathable.
  • High waistband that stays put without squeezing.

The absorbent layers are built right in, so they feel just like regular underwear without the bulk of a pad. I've washed them twice already, and they're still just as soft and comfortable.
