(Not so) fun fact:
Postpartum bleeding and discharge can last up to 6 weeks.
Proof-partum panties can hold up to 4 regular tampons worth of blood.
Changing pads just got well…a lot less necessary. Proof® undies are truly panties with a purpose.
These ultra-absorbent, leakproof underwear are designed with our patented leak-loc™ technology. This innovative moisture-wicking system prevents vaginal bleeding and discharge from escaping the underwear. The best part, is they look like “real” undies but act like an absorbent pad. Finally, postpartum protection that makes you feel comfortable and confident. Lose the pads, get the Proof!

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!”
I purchased these for after baby… And there on after as well. I’m glad I looked at sizing as they definitely run big! In leggings I’m normally a small with belly bandit but after seeing that these run large I ordered the extra small. So glad I did! They fit well, are not tight but the small would’ve definitely been too big! They seem very well-made and I am excited to use these towards the end of my postpartum. As opposed to pads the entire time.
