Smooth-Fit Bamboo Leak-Proof Underwear: Confidence & Comfort

When you think of period or leakproof underwear, what comes to mind? Bulky layers, synthetic fabrics, seams that dig into your hips? We thought so. That’s exactly what we set out to change.

Our best-selling Smooth-Fit underwear has always been about confidence first — a wide waistband that smooths without squeezing, lengths that stay put, and bamboo fabric so soft it’s almost barely there. And now, everything you already love about Smooth-Fit is available with discreet leak protection built in.

Spot the Difference (You Probably Can’t)

At first glance, our new Smooth-Fit Flow Short looks identical to the originals. Same waistband, same sleek silhouette, same ultra-breathable bamboo.

The difference?
A discreet absorbent gusset that holds up to 15ml (≈ 3 tampons). Enough for light leaks and moderate period days — without adding bulk or changing the way they feel.

The New Everyday Essential

The Smooth-Fit Flow range isn’t about changing who you are, or reshaping your body. It’s about giving you the same confidence, comfort, and freedom you already trust — with a little extra protection when you need it most.

Whether it’s light bladder leaks, the first or last days of your cycle, or those unexpected “just in case” moments, you’ll barely notice the difference. And that’s exactly the point.
