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 technical 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.
