Machine wash your undies in cold water on a delicate cycle. Be sure to use gentle laundry detergents. Do not use hot water when soaking/washing as this compromises the undies’ leak-loc™ technology. Once washed, either hang or lay flat to dry. Never use harsh detergents, softeners, or bleach on your proof® undies. The chemicals in those agents can also compromise our undies leak-loc™ technology.
How to keep your undies in tip-top shape:
- Hand rinse in cold water before putting in the washing machine
- Do not twist or ring
- To prolong the life of your undies, use a mesh wash bag
- Never iron, use hot water, harsh detergents, bleach or softeners
- Do not put your proof® undies in the dryer- always hang or lay flat to dry
- To help sanitize, use a few drops of tea tree oil or vinegar in the rinse cycle of your washing machine
- No washing machine? Hand washing in cold water works too!

“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!
