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.
Frequently asked questions
What is the return policy?
We get it ... trying a new kind of underwear can feel risky. That’s why your first pair is fully guaranteed. If it’s not love at first wear, you can return it free of charge — no questions asked.
Since our underwear is a hygiene-sensitive product, it can’t be resold or reused — even if it’s unworn. It will be destroyed.
So take that first pair for a spin. We’re pretty confident you’ll be back for more.
What is it made from?
Wing Shorts are made from 95% bamboo and 5% spandex. Our signature pad holder is made from 100% premium cotton. We make sure to use the finest materials for your comfort and safety.
Does it work with all body types?
Yes! The Wing Bikini is designed to work comfortably across different body types. Its flexible fit adapts to your natural shape, while the built-in pad holder helps keep your pad securely in place without changing how the bikini fits or feels.
