absolutely amazing! I was able to wear these and go an entire shift at work without any leaks.
This Brief will become a staple in your undie drawer!
Our basic brief has a classic fit offering full coverage that flatters all body types. With moderate leak coverage, these undies will draw moisture away from your body with our patented, multi-layer Leak-Loc™ system, while still feeling like your favorite pair. They are slim and highly absorbent to protect you from leaks, day or night.
The Leakproof Brief offers a slim, flexible Leak Proof™ core along the center of the undie. The extended lining offers enhanced leak protection.

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 and cups. The brief holds up to 3 tampons or 6 tsp.
Yes! The brief is created using antimicrobial fibers that inhibit the growth of bacteria and reduces odor. The moisture wicking lining 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 and cups, or replace pads and pantyliners. Proof undies 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 Proof 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. If you have a light to moderate flow, the Brief will handle your flow for an entire day - or night. 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.

I bought this at Target, and it's super comfy, but the gusset needs to be higher in the front for front bleeders, and higher in the back for overnight. I love how the waistband doesn't dig into my tummy fat, but doesn't slide down my hips either.
These panties check every box for me. Comfortable (SUPER comfortable), cute (sexy? can we call period panties sexy?), and they passed the yoga test - upside down and all! I have been curious for years about tampon alternatives, but the period cup just isn’t for me. These panties make me feel so free on my period, and now I never want to be without them🥰.
For women who aren’t quite ready to ditch tampons and free bleed, they will love to wear these as a “backup” plan for accidental leaks.
Wore these while on vacation every day. I just love them, no worries with mishaps!
Didn’t fit my body shape…I usually wear size small. They either stretched out or I had the wrong curves for this style.
Before trying out Proof underwear, I thought they would be bulky, uncomfortable and not be completely protective. However, this was not the case! I have 3 pairs of proof underwear and they are all great but this is my favorite! Not only do they help me stay dry all day long, they are also super comfortable!
I’ve tried other styles and brands. Some feel like gigantic briefs, and some are trying to be too cheeky, which seems impractical for the purpose of leakproof underwear! These are the perfect balance of comfort while still having some style. I absolutely love them.
The Fit is perfect and I have protection from leaks and Cute Panties
Great product and excellent customer service experience!!
Years ago I discovered ICON underwear and loved them, but they quickly changed their style to the point that they were too tight even with a larger size. Eventually, they change names and though improved, they still aren't the same as the originals. Since then I have tried many other brands which just haven't come close and often they don't offer returns which sucks when you're spending approx $35 a pop. I finally found PROOF and they are the best! Better than the original ICONs. I only wish I caught a sweet sale when I made my recent purchases. They launder well and fit better than the day I first tried them on.
With a pair for every flow, you’ll be able to find your Proof™-perfect fit.
