Product Description

So thin, you’ll forget you’re wearing anything. This style has full bum and hip coverage. Our original leakproof technology offers a barely-there feel while absorbing about 1 regular tampon or pantyliner worth of liquid. Patented bonded edges help prevent against side leaks. These underwear feature our signature buttery soft fabric. No show construction is designed to be invisible under clothes, including workout leggings.

Comfort-First Fit

Boyshort silhouette with a mid-rise fit and extra hip and bum coverage.

Worry-Free Protection

Our original leakproof technology provides a barely noticeable feel. Patented bonded edges help prevent side leaks.

Light Absorbency

Absorbs 1 regular tampon worth of liquid—perfect for light flow days, sweat and discharge, and backup protection for heavy flow days.

No-Show Style

Buttery-soft and smooth fabric gives a seamless look and feel. Disappears under clothes, even leggings.

Easy to Wash

Machine washable just like regular underwear.
