Works Great
They are effective and comfortable
Attention fellow bleeders! We've got something exciting to share! Our fabulous Leakproof Brief in Moderate absorbency, the undies that will make your period days a breeze!
These undies are the real MVP of your underwear drawer. They're mid-rise, so they'll flatter all body types and provide full coverage. And, let's be honest, we all need a little extra coverage during that time of the month, am I right?
But here's the kicker: our Leakproof Brief features our patented, multi-layer Leak-Loc® technology. That means you can say goodbye to leaks and hello to peace of mind - day or night! And don't worry, they're not bulky or uncomfortable, these undies have a slim profile and feel just like your favorite pair of undies.
The best part? They're washable and reusable! So, add these undies to your period regimen, use them as a backup, or an alternative to pads and tampons. Trust us, your period game will never be the same again!
The Brief offers a slim, flexible Leak Proof™ core along the center of the undie. Extended coverage comes further up the front and back for enhanced protection.

Caring for your pair is easy. Machine wash cold with mild detergents on a delicate cycle, then hang or lay flat to dry.
The Leakproof Brief is perfect for moderate periods, light bladder leaks, sweat, spotting, discharge, and everyday wear. You’ll love it for replacing pads and pantyliners, and to replace or back up tampons. The brief holds up to 3 tampons or 6 tsp.
Yes! The brief is created using fabric that helps fight odors. The moisture wicking lining helps pulls moisture - including sweat - away from the body and into the leakproof core, helping you to feel dry and comfortable.
The Leakproof Brief by Proof® can be used to replace or back up tampons, pads and pantyliners. Proof undies are designed to help pull liquid into the absorbent core, so layering a pad over the gusset will not allow Proof® to do it’s *super absorbent, moisture wicking* magic.
The Leakproof Brief was designed for periods. We created Proof® undies in a variety of absorbencies, so that you can find the best fit for your flow. The Brief absorbs up to 3 regular tampons’ worth of liquid or 6 tsp. We recommend wearing a pair of Proof in the right absorbency level for 12 hours, and then changing like you typically would after a shower, after getting up in the morning, or before going to bed in the evening.
Proof’s patented Leak-Loc® technology protects against all of life’s leaks, both big and small. Our undies hold up to 10 teaspoons (that’s 5 full tampons worth!) of liquid.
They are effective and comfortable
These arrived just in time — truly ! My first and second day are always my heaviest flow wise and these undergarments held up to the task that usually takes 3 tampons! I wish I could have gotten the black ones instead but I love these and can’t wait to use them next! 10/10 for comfortability too!
They are comfy, and work so well. I ordered these for my teen daughter and just bought a set for myself
I have worn a few different ones and this is the best fitting and the most comfortable.
I was surprised at how lightweight these felt.
I Like The Fit Yet Seems My Pants STILL Get Moisture On Them Through The Leak Proof Underwear :(
Hi Caroline:
Thanks for your feedback, the Brief is a moderate in terms of absorbency. You may want to try a heavier absorbency like the bikini or the mesh hipster. I hope that helps!
Very comfortable, Use size chart for a perfect fit. Great fabric.
These undies are fantastic! I want to replace all my undies with this style - great quality and they are cute! Win win.
Fit is like having nothing on! So soft and smooth. And the whole purpose, absorbs beautifully.
Thank you!
Wore these for hours with a heavy flow and no complaints as far as leaks BUT they were super uncomfortable. I have the thong and brief and love them, but these didn’t work for me.
With a pair for every flow, you’ll be able to find your Proof™-perfect fit.
