FAQs

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.
