For all of life's leaks, you've got Proof

We meticulously designed our leakproof undies to keep you protected from any leak life throws at you - from periods, to pregnancy, to bladder leaks and beyond. Plus, when you switch to reusable Proof undies, you're helping to keep single-use plastic products out of landfills (how's that for a win-win?!)

"The Best Period Underwear, According to Women Who Wear Them"

"The super absorbent fabric is the best thing to have on without having to worry about toxic shock syndrome or multiple trips to the bathroom."

"Go about your day in comfort even on the heaviest days of your period. This pair sits high on the hips so it won't roll down, features breathable mesh sides that add a little style factor, plus offers complete leakproof protection!" (The Mesh Hipster)

"The most absorbent period panty on the market."

Go with your flow

There's Proof for every phase of your flow, from surprise sprinkles when you sneeze to super heavy periods and beyond.

“These panties are so incredibly comfortable!! Super soft and literally no panty line. They stay in place too! They have an extra "leak" layer that is comfortable and not bulky at all (think protection of panty liner without the feeling of a panty liner.) I ordered a small and they fit great. For reference, I am 5'2" 125 lbs. Great purchase!”

Wonderful!!
“I have reached early menopause but other things happen down there. (During workouts are the worst) I got these to help with my bladder leak and sweat. To my surprise, they also made my bike seat a bit more comfortable. Ha. I plan on getting another set of them.”

Proof Brief
“I get the worst periods ever, and I have tried every brand of period underwear out there, and nothing has been leak proof (as they claim). Needless to say, I was skeptical when I bought these, but figured it was worth a try. I truly cannot believe how well they worked. No leaks whatsoever and super comfortable too! If anyone out there has a heavy flow, I highly suggest this brand. They are worth every penny!”

GAMECHANGER!
“I've been really struggling with yeast and discharge during my pregnancy and these panties have been really great. Sometimes I change my underwear 4 times a day because I just feel wet; not with these. They really don't leak through to my outer clothes.”

DO exactly what they say
“These lightweight thongs are another one of my favorites. They are light, comfortable and offer me the security that I need on my spotting/light days. Honestly, it's so much better than wearing and wasting a pantyliner when I'm spotting. Also, it saves me the discomfort of chafing from pads and liners. I honestly forget that im wearing the thongs because they are so comfy and light. Honestly, I could use a full drawer of these. 😊”

“I wear mine after sex to clean up... messes. (You know!) I don’t think I’ll ever go back to normal undies.”
