Wing Bikini

1/8

Wing Bikini Designed to keep your pad locked in so you can flow in peace.

Our Lock & Flow™ system pairs buttery-soft bamboo with a peach-fuzz waistband that’s gentle on bloated tummies — and a first-of-its-kind pad holder that keeps your pad locked in place, no more sideways sliding or constant readjusting every time you sit, stand, or move.

How it works

Pad. Lock. Go.

Your pad, held exactly where you put it. Three seconds, every time.

01

Pad

Lay it in

Place your pad along the inner panel, sticky side down. Same pad you already use.

02

Lock

Fold the wings

Tuck the wings through the inner holder. They grip the pad, not your skin.

03

Go

Forget about it

No shifting, no bunching, no midday check. Wear it like normal underwear.

What makes Calin Special?

NO MORE READJUSTING SHIFTING PADS

Includes our signature Pad Holder- a cleverly sewn-in cotton piece on the gusset that locks your pad in place the way an anchor stops a ship. No more accidental leaks, sideways sliding or constant readjusting every time you sit, stand, or move.

NEVER ASK IF ANYTHING IS SHOWING AGAIN

Our design gives you extra protection against blood spots, accidental pad shifts, and leaks. So even on your heaviest days, you can move, sit, and sleep with more peace of mind knowing you have an extra layer of protection where you need it most.

A COMFY HUG WHEN YOU NEED IT MOST

Our ultra-soft cotton has a snug fit, providing very light compression to ease menstrual pains and keep everything together, including your mood swings.
