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

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.

    Boyshort just ok

    I own over 30 pairs of these and while they do assist during leaks their coverage in the front is underwhelming. The need more material covering the private areas and leakage coverage a bit higher than provided.

    Even More Comfortable!

    It's been a couple of years since I ordered my last Boyshorts. I wash them on my wool cycle, hang them to dry, and they last really well! So, I was pleasantly surprised when I ordered the 3-pack, to find the fit and stretch even better than before. Still my faves after many years.

    Crotch panel too narrow

    I have bought several of these panties and for the most part, I really like them. But…. I am finding that the crotch panel is just too narrow. If they were just a half inch wider they would be perfect.

    Definitely not leakproof

    I would rate the comfort and fit excellent. But the « leakproof » aspect of it is terrible. I wore these on a walk with my kids and the sweat went through…I couldn’t even imagine if I was on my period. Very disappointed for the price.
