Get accurate measurements, we recommend you re-check your size with every purchase..
For most of our styles, the most important measurement is your hip size to get the right fit. It is also useful to check your waist measurement for certain styles. Please take a look at the product description for a guide.
If you're in between sizes, we suggest sizing up (e.g. from a size 10 to 12) for ultimate comfort.
1. Place Your Feet Together
Having your feet apart can give a measurement that is actually larger than your hip area.
2. Waist
Your natural waist measurement should be taken at the narrowest part of your torso. This is where your body curves in and is often at or above your belly button.
3. Hip
Your hip measurements should be taken at the fullest part of your hips.

We know this might feel risky
We get it. Trying something new, especially when it comes to period care. But with [pee chee cheex], you have
nothing to worry about.
Here’s why:
With our 60 day Risk-Free Guarantee for all multipacks, you can try [pee chee cheex] with no dramas. No pressure. Try just one pair from a multipack, and if you don’t love it, return the unopened undies for a full refund.
See? No pressure at all.
And guess what? We’re adding FREE Shipping and Returns on any multipack too!
So, with nothing to lose, let’s take a look at why [pee chee cheex] multipacks are the smart choice.
Stop Throwing Away Money on Disposables—Choose the Smarter Option
Most of us spend $15 to $20 on disposables, every month—that’s over $200 a year, literally tossed away on single-use products. And that doesn’t even include the cost of replacing stained underwear and towels from leaks.
A [pee chee cheex] multipack is just under $150. So naturally, switching to a multipack pays for itself over and over again.
Not wasting feels good. But being ready for anything your vagina throws at you… that’s the game-changer.
So…
One Pair Will NOT Do It
Sure, one pair might get you started, but it’s not enough for your whole period. Imagine running out mid-cycle—scrambling back to disposables? No thanks!
That’s why a multipack gives you freedom and confidence for your entire cycle—whether it’s a light day or a heavy one. Never worry about running out or having to go backwards and resort to disposables – again!
You Can’t Get Simpler
Think about it: with a multipack, you’ll always have a fresh pair ready. No more last-minute panics, no more waiting for that one pair to dry. Just grab, wear, and go.
It’s like slipping into your comfiest undies, but with built-in period protection.
When it’s this easy, can you really imagine going back?
You Don’t Need to Make Trade-offs
Let’s be real: you don’t need to juggle tampons AND pads just to feel safe. [pee chee cheex] multipacks gives you full, comfortable, leak-proof protection. No more juggling multiple items. No more panty liners. Get peace of mind that comes with reliable protection, in one product.
Here’s where it gets even better: by choosing Pee Chee Cheex,
You’re Embracing a Natural Solution
…that doesn’t stick around for centuries like disposables do. When you Switch & Save with multipacks, you’re not just saving money—you’re saving the planet. Each pair is 85% compostable and biodegradable, ensuring that when they’re done, they return to the earth instead of polluting it for generations.
Every small step adds up. Start today - choose one multipack here and join [pee chee cheex] community - making a real difference, one period at a time.
Had a hectic day—flying interstate, client meetings, and a workout—all while on my period. Usually, I'd be juggling pads and loo breaks, but PeeChee Cheex changed that. Wore them all day, from the flight to the workout, and they held up amazing. No leaks, no discomfort. These undies made my busy days heaps easier.

MORE THAN 2.3 MILLION AUSTRALIANS SUFFER FROM MENSTRUAL PROBLEMS
32% of Australian women suffer from period problems. They might need to change their pads or tampons every hour, or even more often. Some require extra protection for heavy flows. And dealing with breakthrough bleeds means they frequently have to buy new clothes once or twice a year. Wouldn't it be nice if your period undie was part of the solution?
Best purchase I've ever made! It was so convenient not to have to keep changing a pad :) Periods were such a pain, so uncomfortable and embarrassing before, but wearing pee chee cheex makes it feel like I'm not even menstruating at all!!

MOST DISPOSABLE PERIOD PRODUCTS (COMPANIES) ARE FULL OF IT - ARTIFICIAL PROMISES
For years, other period product companies have been putting more artificial chemicals into their product - nasty chemicals like odour management chemicals, PFAS, PFOA, PFCs, Phthalates, VOCs... they promise more and give you less care.

YOUR PERIOD UNDIE QUESTIONS, ANSWERED
They're a total game changer!
First things first, they're machine-washable and reusable, so you can kiss those single-use disposable panty liners, tampons, and pads goodbye. Not only are they designed to protect you, but it's also designed to protect the planet.
[pee chee cheex] undies come in a range of absorbencies, from regular to super heavy, so you'll be covered no matter what stage of the cycle you're in. And they've got innovative built-in technology that includes a 2-in-1 moisture-wicking top and bottom layer, a super absorbent core, and quad barriers engineered to protect against leaks. That means you can wear them with confidence, knowing that they've got you covered.
Speaking of coverage, [pee chee cheex] period undies are rigorously tested to make sure they really work. And they're made with high-quality fabrics like Lenzing Modal, which is breathable, unfavourable for bacterial growth, and moisture-managing. Plus, it feels silky smooth and gentle on your skin, which is always a plus.
One of the best things about [pee chee cheex] period undies is the super absorbent core, WITHOUT adding harsh chemicals to treat fabrics. We take advantage of the natural benefits of bamboo. It draws your flow away from your skin and locks it away with quad barriers that protect against leaks. We've even added extra protection in those common leakage points between the legs, so you don't have to worry about a thing. Give 'em a go and see how much better you feel!
Everyone's period is different, and every day can feel like a mixed bag. The best thing about [pee chee cheex] is you can wear them for much longer than regular pads. They don't feel like you're carrying a brick in your undies like pads can, which is just plain uncomfortable. The super absorbent core is made of premium natural fabrics, so they don't expand when saturated like pads do. You can wear your [pee chee cheex] undies for as long as your daily flow allows. But, make sure you choose the right style, as some styles are more absorbent than others. We rate our undies by absorbency, with our highest absorbency styles holding up to 12 tampons worth of flow. Feeling a bit damp? It's time to change into a fresh pair, no ifs, no buts.
You might be wondering, "How many pairs do I need?" If you're not sure, play it safe and change them as often as you would a pad. That might be every two hours or every six to eight hours, depending on your flow. Our advice? Start with a 4-pack, so you have spares on hand, and don't have to do extra laundry every night. [pee chee cheex] is here to make your period care changes convenient, easy and as comfy as possible. Trust what they say, you'll never look back!
Alrighty, when it comes to getting the right size for your [pee chee cheex] undies, we recommend you first measure your hips. Make sure you measure the fullest part of your hips, including your cheeks. That way you'll get the perfect fit. In addition, we recommend you also check your waist measurement, on our Size Chart here If you're in-between sizes, we suggest sizing up (e.g. from a size 10 to 12) for ultimate comfort. Your [pee chee cheex] undies are made to stretch, so they should feel just right. And hey, remember our 60 Day Risk-Free Guarantee for new customers: if your first pair doesn't fit, we'll send you the right size. Head over to the 60 Day Risk-Free Guarantee details to read all about it!
Looking after your [pee chee cheex] undies is a breeze. Once you feel a bit damp, just swap into a fresh pair. Then rinse the worn pair in cold water (until clear) to remove most of the blood, and pop them in a mesh bag to wash.
To keep your [pee chee cheex] undies in tip-top condition, wash them in cold water on a gentle cycle and hang them out to dry. It's that simple! Avoid using bleach, fabric softeners, and the dryer to ensure they last as long as your regular undies and work at their best. If you want them to dry faster, flip them inside out with the gusset facing out and hang them up in the shade with a good breeze.
Handy tip: To conserve water, rinse them in a washing bucket while you're having a shower or save a few pairs to wash all at once. Easy as pie, and you'll be doing your part for the planet too!
Our [pee chee cheex] period undies come in different levels of absorbency, from Regular-Heavy, which can handle up to 8 regular tampons worth of flow, to Super-Heavy, which can take care of up to 12 regular tampons worth of flow. So, you're sorted for every day of your cycle, no matter how heavy or light your flow is. To make sure you get the most out of your [pee chee cheex] undies, we recommend trying them out at home first so you can see how they work. Once they start feeling damp, it's time to change into a fresh pair. If you're new to [pee chee cheex], we recommend grabbing at least a multipack of 4 undies so you're always sorted during your cycle. Who wants to do extra laundry during that time, right? Plus, we've got Switch & Save multipacks (with our 60 Day Risk-Free Guarantee) that let you build up your [pee chee cheex] collection and save some 'moolah' over the lifetime of your periods.

LIKE BRIDGET, WE WORRY ABOUT EVERYTHING (comfort, leaks, security, safety… weight… oh dear) SO YOU DON’T HAVE TO
Sounds all too familiar? We know it’s bloody frustrating! There’s a lack of decent options when it comes to period care.
We just want something that's comfy, "really" works well, and feels clean and eco-friendly, right?
So, we decided to create our own period undies that tick all those boxes –
Undies that will change your life (literally).
It's a better option for our families, without all the drama and hassle of dealing with so many problems. After our team invested 19,000+ hours collectively (57 different designs and construction methods, 49 different fabrics), 3+ years in the making… the world's best period undie.
* Our fabrics are sourced from suppliers who adhere to Oeko-Tex standards, ensuring safety and environmental responsibility in their manufacturing processes.
I absolutely love these. I have actually said to my partner that for the first time in my life I am looking forward to my period. They have become my go-to underwear for every occasion, regardless whether that time of the month has arrived or not....walking the dog, working in the office, lazing around.
I bought these to test if they are a good option for my tween who has not yet started her cycle. They are great! Snug yet comfortable fit, I feel dry and fresh even through yoga and high intensity workouts.
I was a bit skeptical at first but after reading positive reviews I thought I'd give it a try. Holds your period well and keeps you feeling dry all day. It was also very easy to wash and I love the natural material it's made from because it's quite soft!
Bought these as I work in early childcare, so lots of picking up kids, jumping around, dancing and laughing which all can trigger a small leak. Was tentative about these, so decided to buy a pack and test out one pair on their risk-free guarantee. Well, after one day at work with no embarrassing moments, I decided to keep the rest.
