FAQs

Proof’s bikini underwear offers comfort and invisible protection. With three different styles to choose from, you can find the pair that’s just right for you. Bikini underwear typically has a lower rise on the hip, minimal coverage in the front, and a higher cut on the legs. All the while, they still offer plenty of coverage on the backside. Bikini underwear is one of the most popular styles for women, as it goes with just about any everyday outfit thanks to its flattering cut. Proof offers 3 types of bikini underwear that can all keep you leak-free and confident.

Leakproof Bikini Underwear (heavy absorbency)
Leak-Resistant Everyday Bikini (super-light absorbency)
Leak Proof® Lace Back Bikini (moderate absorbency)

Let’s face it - leaks happen. So why not be protected? With Proof’s Lace Back Bikini Underwear you can take on everyday life and never get the fear of leaks getting in the way. Proof’s Lace Back Leak Proof Bikini Underwear is best for:

Moderate periods
Light bladder leaks
Pad replacement
Back up for a tampon or cup
Sweat
Odor reduction

Yes, our Leak Proof® Lace Back Bikini Undies feature odor reduction technology. We use antimicrobial fibers to help reduce odor. Just another way you can boost your confidence with Proof.

First, measure your hips and waist. To measure your hips, lean over to one side. Find where your body naturally creases and place the tape there. You will measure parallel to the ground. To measure your hips, turn to the side, take a second to enjoy the view, and locate the fullest part of your booty. Again measure parallel to the floor while placing the tape around the fullest part of your hips and tush. Once you have your measurements, you can use Proof’s size chart to determine the appropriate size.

Falling in between sizes? Go with the size that matches your hip measurement for the most accuracy.

Yes! Proof Lace Back Bikini undies are made with several layers of moisture-wicking, absorbent material. They are designed to extract moisture from the body and into the extra absorbent core of the undies.

Free yourself of uncomfortable tampons and crinkly pads with Proof’s Lace Back undies. You can use Proof’s Lace Back undies as a replacement or back up for tampons, pads, or a cup. They are best for moderate periods so if your flow is heavy, you should try our classic leakproof undies.

The proof is in our reviews. Our Lace Back Leak Proof® Bikini undie reviews highlight that they are “surprisingly comfortable,” “sexy,” “comfy and cute,” “highly absorbent,” and more. Find out for yourself just how comfortable and confident our Lack Back Leakproof undies can make you feel.

See The Proof

Proof’s patented Leak-Loc™ technology protects against all of life’s leaks, both big and small. Our undies hold up to 10 teaspoons (that’s 5 full tampons worth!) of liquid.

Feeling Sexy

The Lace Back panty is great! You can still feel sexy even while being protected from leak problems. Who can feel sexy if you have on a bulky pad? I don't care how they are advertised, pads are always bulky. I usually wear the leak proof thong, but once in a while I want something different. I don't see the panty line, I feel sexy and protected at the same time. Thank you Proof!

Saving Money!

I absolutely love my Proof products. I love being able to be comfy, and cute, while not having to spend so much cash on disposable menstrual products!

Love Them!

So far, I have really enjoyed my proof products! They are highly absorbent and I don’t have to worry about any leakage. I would forget I’m on my period if it weren’t for the cramps. It’s convenient and an eco friendly alternative.

OBSESSED How are these period underwear???

I've been obsessed with Proof since I first tried them and honestly didn't think I could love them any more but this new lace style is AMAZING! I truly can't believe these are period underwear because they're cuter than any of the underwear I've ever had. I love these!

So beautiful!

Love this new style! Surprisingly comfortable. Didn't think I could feel this confident and look this good during this time of the month. I'll be wearing these all the time, not just while on my period.

Sexy New Staple
