Perfect for my light days. I loved them w my leggings. No panty lines!
monica B
Leak-Resistant Everyday Brief
I bought 5 different ones
These undies are great!They have changed my life
Ragna T
Leak-Resistant Everyday Brief
Just bought my 2nd pair!
I can't overstate how much I love these. Super comfortable, works perfectly, and
minimizes the amount of planning I have to do around my period. I only wish
middle-school me could have had these!I wear size Medium and am ~150lbs.
K
High-Rise Brief
Sleep comfy
I had a great night's sleep on the second day of my period. No leaks with only
the underwear.
Agata A

Leakproof Bikini Underwear
Life changers
These are seriously great underwear, and provide assurance against spotting
without the inconvenience or mess of a pad. Wish I'd tried them sooner!
Amanda C
Leak-Resistant Everyday Brief
My Coachella Lifesaver
What a lifesaver this leakproof nude thong is - I packed 3 days of outfits in
light/white bottoms for Coachella and then my heart sank when I realized my
period was going to come any day that weekend. Even with tampons I leak on my
first days, so ordering 3 of these nude thongs SAVED me! I was able to still
wear all 3 outfits without the worry of staining my clothes, and they stayed dry
when (sure enough) I did start to leak on day 2 . Could not recommend this thong
enough-especially as a summer staple when basically every outfit calls for
no-show nude underwear!
Leah
Leakproof Thong
Worry Free
Wore these while on vacation every day. I just love them, no worries with
mishaps!
Jeanne K
Leakproof Brief
Comfort and Confidence
These are so comfortable that I wear them even when I don’t have my period. They
give me the security that I need without feeling bulky. I’ll definitely be
getting more colors and styles.
Debbie
Leak-resistant Everyday Bikini
Sexy New Staple
I'm delighted to find such a sexy and protective pair of period undies! They are
just beautiful and I feel amazing in them. How genius of Proof to design leak
proof panties that look like gorgeous lingerie.
jG
Leakproof Lace Back Bikini
WOW What a find!
Where have these been all my life? Wish they had been around when I was
menstruating but they are a lucky find for my post menopausal bladder leakage. I
purchased the light and mid flow versions and have not been disappointed!
Becky C
Leakproof Bikini Underwear
Powerful Panties
There’s nothing more powerful than free bleeding. I’m not kidding when I tell
you about the power these sustainable and leak proof period panties hold. They
make me feel beautiful and comfortable while I bleed. And coming from a gal with
an extremely heavy period they really do work. Not to mention they are better
for the environment while saving you money and a trip to the store to buy new
products every month.
Birdie
Leakproof Hipster Underwear
Legit!
Love this thong! I was skeptical about how well it would hold up when I dance
and do active things, but it's legit!
Luci
Leakproof Thong
Amazing!
Sooo lightweight! I love how comfortable these are! They are so soft and I just
feel great wearing them! They look great and offer great protection, too!
Michelle M
Leakproof Bikini Underwear
Once you go Proof…you’ll never go back!
For the past 2-3 years I’ve wanted to be done with pads and tampons. Let’s face
it, they are ancient and with all the new technology, there is no reason to hold
on to them. Yet, every alternative that I researched kept missing the mark.
Don’t even get my started on those cups okay. I’ve been wanting to try the
leakproof underwear but I wasn’t convinced they would give me what I was looking
for. Yet, every cycle I grew more and more in my disdain for products that I
would wear panty liners and layer my underwear and clothing just to avoid the
bulkiness and discomfort of pads and tampons. Simply put I wanted to feel free.
I researched the leakproof underwear again and decided to give it a try. I
started with two because the prices were $30-$35 (moderate and heavy flow
options) and I didn’t want to waste money on something that didn’t work.
Listen!!! This purchase exceeded my expectations. The panties are comfortable,
stretchy and secure. The absorption is unbelievable. I feel completely
liberated! It’s magical. They feel better than my regular underwear. I will
never go back to living in the Stone Age!! I went 6-7 hours in each and there is
no wetness, no odor, no residue. NOTHING. Looks and feels like a fresh pair of
underwear! I got a size medium and I have a lot of booty but it covered my
backside. There was no bunching or wedging. Now that I know they work I
recommend buying at least 4 but y’all need to have some discounts. Buy 3 get one
free perhaps?? Two is just not enough and I had to resort to washing them every
day after use. I’d complain about the price but they are an investment
considering I never have to purchase pads/tampons again. READ MY LIPS…I will
never go back!! You hear me!! NEVER! Do yourself a solid and step into the new
age. Your girl deserves better and so do you!!

Stress Free
I can sleep stress free knowing everything is staying in place AND if anything
does get out my panties are here to keep me…and my bed sheets, free of the big
red dot .⁣

Leakproof Hipster Underwear
Where have these been all my life?
No more liners and waste for me! As someone with a chaotic and irregular cycle
my whole life, it was always a guessing game when shark week would start and
liners were sadly a daily must as a safety measure. These have lasted me several
months so far, with no sign of wear on them yet. I love them and am buying
another weeks supply to make them a permanent edition.

Leakproof Thong
Really Great Tool
This has proven to be worth every dollar. It has helped alleviate that anxiety
we all feel while on our period hoping not to leak through. Super comfortable,
feel like any other pair of underwear.

Great for the Mom life
After birthday two kids, trips to the gym can be... leaky. This saves the day,
and no lines in the gym pants! Ordering more.

Bye Bye Pads
Hello leakproof thong! I am SO happy with this thong. I normally have to wrap a
pad or panty liner around my thong as a back up to my tampons, but no more weird
bunching under my clothes with this baby. Thanks Proof!

Great Protection
I am in my 60’s and I am experiencing some bladder leaks. This underwear is not
only comfortable but keeps me dry all day into the evening, My only complaint is
that I wish they had more of the Black briefs in stock!

Leak-resistant Everyday Bikini
So comfy
This bra literally feels like you aren't wearing anything, while still being
moderately supportive and giving coverage to the nips.

you have questions, we have answers
Will period undies smell after use?
Proof® undies are equipped with a moisture-wicking lining that helps fight
odors.

If you want, simply add a few drops of vinegar or tea tree oil to your washing
machine during the rinse cycle and complete washing as normal.
Help! I have a super heavy flow. Which style is best for me?
Proof® period undies were designed to handle even the heaviest of flows.

The Hipster features our super-absorbent core that holds up to 5 regular tampons
and front-to-back protection—great for overnight!

Other heavy flow favorites: The Bikini and The Mesh Hipster.
Can Proof® undies be used as an alternative to pads, tampons, or cups?
Yes!

Depending on your chosen absorbency level, our leak-resistant and leakproof
styles can hold anywhere from 1 light tampon to 5 regular tampons' worth of
liquid.

You may also feel more comfortable using Proof® undies as a backup to a
menstrual cup or tampon.
How do I care for my Proof® undies?
Proof® undies should be washed gently. Simply toss in the washing machine on a
delicate cycle using cold water and mild detergents. Hang or lay flat to dry.
