MACHINE WASH COLD
Proof undies have strong protection, but should be washed gently. Machine wash in cold water on a delicate cycle, using gentle detergents. To sanitize and refresh, use a few drops of tea tree oil or vinegar in the rinse cycle of your washing machine. Hand washing in cold water works, too!
DO NOT USE
Do not use hot water, harsh detergents, softeners, or bleach when washing as these may compromise the Leak-Loc™ technology.
HANG UNTIL DRY
Once finished washing, hang or lay flat to dry. Depending on absorbency level, Proof’s multilayered technology can take between 6-24 hours to dry. To dry more quickly, blot any excess moisture and hang dry.

“So great!! If you’re thinking about getting these just do it! So comfortable and protective. Will be ordering more for sure.”
“Now my period underwear are my favorite underwear”
“I’ve used other period underwear before and I was shocked at how much better these were — I used to bring 2+ pairs of the other brand just in case. I was more than fine with one pair of Proof® underwear!”
Like others stated these run a tad big so I got an XS instead of a S and they fit great. Love the material, very comfy.
Perfect for spotting. So tired of liners. Its so nice to wear the nude color with light colored clothing and not worry. Two thumbs up!
Being pregnant with baby #2 I have struggled with bladder leaks. I am no longer afraid to sneeze or laugh at work. I recently purchased the proof thong and I am so glad I did. It is absorbent but so comfortable, and no panty lines is a bonus!! I wish I would have bought them sooner
Great panties! I have two pairs on the thongs and 28 weeks pregnant. Keeps the leaks to myself!
