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!”
These are SUPER comfy but they do roll down on the bottom of my bump.
Super comfy! Love the material.
I'm a first time pregnant lady and the experience of daily leakage is new. By the end of the day I would be wet and odorous--not fun. I bought these on a prayer and hope and they did not disappoint. They eliminated that weird, tangy smell I've had ever since conceiving (thought that would just be there the whole 9 months) and at the end of the day I'm dry! It's delightful. I do have a short torso and my belly has rounded out a lot so the top of the panties roll in the front for me, but I have no visible panty lines and they're crazy comfortable even for us delightful thick ladies. :) I highly recommend and have already ordered more--they're worth it!
Maybe TMI but here goes. This is my 3rd pregnancy and for whatever reason this time around I’ve been prone to yeast infections. I wear a line throughout pregnancy due to discharge but when I start to get a yeast infection even a thin liner becomes so uncomfortable I would have a hard time walking because it would hurt so badly. I came across these and thought I’d try them and holy moly I was so happy! The liner in them is just enough for everyday needs and because it’s the material of the undies, I don’t have that extreme discomfort wearing a liner. And some people mentioned it wasn’t for large gushes and while that is probably true I will also share that I was at the back of a target and felt a large amount of discharge/fluid, like I was sure within seconds I was going to have a spot on my leggings that would be visible. Quickly went to the front of the store to the bathroom to assess the damage and I could not believe there was none!!! The liner on these undies had soaked that all up!! So happy I found these and if your lady parts are extra sensitive I can’t recommend trying these enough!
