Yes, it aaaactually works! We stand behind our products 100%! As long as you pair the right protection level with your flow (i.e., Super protection on those first few heavy days) you can wear our undies up to 12 hours worry free!
Make sure to rinse the underwear immediately after you use them, if you can't put them in the washing machine right away, let them hang dry, until you are ready to wash. Don't let them hang for more than 2-3 days before washing.
Flows are subjective! So, when trying out leak proof underwear for the first time, check your undies every hour to make sure that they are doing well. Have a look to see if the blood is consistently getting closer to the edge of the gusset. You may find out that you might need a higher or lower level of protection than expected!
Typically, you can feel the underwear reaching that point of getting ready to change. It's kind of an intuitive thing, just like pads!
We say that our undies can last up to 12 hours because that's a real number! Our underwear is lab-tested with blood at a consistent drip for a total of 8 hours (a workday.) The Ultra - Charlie was able to hold 120ml in 8 hours, and still could keep going!
You may need to change them more frequently than 12 hours (especially on really heavy days) because our bodies can offload a ton all at once.
You won't feel wet, the underwear doesn't get heavier, and nothing swells up. It literally just feels like wearing underwear!
Everything gets absorbed and you feel dry and comfortable the whole time! Our natural bamboo fabric is breathable, helps to prevent bacteria growth and locks in odour, so you'll feel dry & clean all day!
Our Ultra protection was made for you! If you have to change your other products (tampons, pads, cup) every 1.5-2hrs, then these will be life changing! They’re also great for Fibroids, PCOS, Endometriosis, or simply genetics!
Check out our Ultra protection options on our shop page!
While we initially developed our underwear specifically for periods, they are also great at preventing leaks of all kinds!
Yes! ALL of our underwear (other than our thong styles) have the leak proof layer going all the way up the back and the front, so you’re 100% covered!
Our natural bamboo fabric is breathable, helps to prevent bacteria growth and locks in odour, so you won't smell as long as the proper care is followed!
Nope! Our undies are designed with heavy flows in mind!
While wearing a tampon in tandem with our undies is fine, a pad is definitely not recommended as you’d be limited to the absorbency of the pad, and not our super absorbent underwear! You’d just be covering up the great gusset protection.
We've designed our undies with the heaviest flows in mind - when you solve leak proof protection for heavy flows, you solve it for light flows as well!
All of our styles work for lighter flow days and the great thing about each style is they aren't bulky so no matter what flow you are , you can feel comfy and confident!
Check out the Regular collection because more coverage means more absorbency, but offers that same thin, lightweight leak protection as the light styles, making it great for light AND regular flows!
Yes! Our undies have always been and always will be PFAS free!
What does PFAS free mean? It means that our products have been rigorously third-party tested for PFAS and are certified PFAS-free (non-detectable over 30 parts per million.)
PFAS can be absorbed through the skin and have been shown to have negative effects on human health. Typically, it's found in non-stick cookware or food packaging, but can also be present in waterproofing finishes used in clothing manufacturing (which we have never used!)
For more details on our leak proof layer, check out Our Tech, Our Planet page!
All of our materials are OEKO-TEX Certified and tested safe. Our undies have always been and always will be PFAS undetectable! You can see the full breakdown on Our Tech, Our Planet page!
Our bamboo fabric is made using a mechanical process and natural enzymes to extract fibres, similar to how linen is made.
This process isn't as common because it takes a little more time, effort, and cost, but the result is soft, high-quality bamboo fibres you’ll love wearing. Worth every second! This also categorizes our fibres as purely bamboo, not viscose or rayon from bamboo.
No, our undies contain spandex (elastane), which doesn't contain any latex!
Yes! We always are looking for new retail partners! Send us an email to let us know which stores you'd like to see us in at hello@revolcares.com!
The most impactful thing you can do is reach out to your favourite store directly to ask them about carrying our products!
Our Retail Exclusive line was specifically developed to be sold in stores at an accessible price point, keeping absorption the same but simplifying the styles to be more approachable and adaptable to first time shoppers.
Think of our retail styles as your favourite black t-shirt that goes with everything.
Our online-only styles offer more variety to suit personal needs like specific fits, varying protection levels and colours.
Think of these online styles as that jacket that shows your personality and makes you stand a little taller.

We LOVE that you love these bras - they're truly so cute! At this time, we are focusing our future innovations on offering the best leakproof underwear out there!
We're constantly innovating, and we've received this question often!
Be sure to stay tuned to our email list as there will be more info to come on this for 2026!
We totally get that you want to have the freedom of swimming while on your period! While our super absorbent natural fibre pad and fabrics are fantastic in a dry environment, in a wet environment, water takes out the ability to absorb anything else, which could then cause leakage to the sides.
All other period underwear brands that carry period swimwear only offer light protection because of this. They are also made with polyester gussets, which dry much faster, but still wouldn’t totally prevent leakage while getting out of the water.
If you really want to wear our undies while swimming, a better choice would be one of our Regular or Light pairs which doesn't include the absorbent pad, just the leak proof layer and absorbent fabric!
We are constantly blown away with the support from our community when we launch a new product and style. We completely understand your frustration when your favourite style and size is out of stock so we're working as fast as possible to get our undies back in stock and online for you!
Make sure to sign up for the restock notifications on each product page to be the first notified of your size back in stock!
Some of our styles may fit a little big (particularly the plus sizes), but you can double check by going to our size chart here!
Our sizing is ALWAYS inclusive, so we offer sizes from XXS-XL & 1X-7X!
If you are looking at our thong undies, then go by your waist measurement. For our plus-sizes, most people can size down.
It all depends on how you want your undies to fit! (eg. if you get bloated on your period and don't like your undies tighter, you might want to size up!)
They do not shrink much if you follow the correct care instructions! They have a lot of stretch, so should maintain their size fairly well.
We have sizes starting at XXS for a few styles.

Yes! We recommend washing your undies once before first use. This helps activate the bamboo fabric and ensures the absorbency works at its best.
We recommend rinsing them immediately after use with a little bit of soap (dish soap works well to break down the enzymes found in blood). Then, machine wash on regular, and hang to dry.
For super detailed instructions, please check out our Care page!
Fun fact! It just means your vagina is healthy! Many people's pH of their discharge/menstrual blood/urine is slightly acidic.
This acidity can interact with the dye of the underwear's fabric. So, if you've been primarily wearing synthetic or light-coloured undies and you haven't seen this before, it's totally normal!
To prevent bleach staining, make sure to rinse out your undies ASAP in cold water with a liquid dish soap, or you can use enzymatic stain removers.
No! They'll be fine, just make sure they get a good soak in water (and you can also throw in a couple tablespoons of vinegar) to help break up the stain from the fabric and then do the pre-wash, then throw it in the machine as normal.
We get that life and executive dysfunction can get in the way, but because our bamboo and cotton gussets are naturally anti-microbial, you're good, just don't leave it for too long!
