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.

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!!

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.

Want an example... Let us break it down for ya - If you, as a first time customer, order a 4-pack of undies, we recommend you try one pair on to make sure they are right for you. If you don't love that pair, keep that one, and return the 3 unopened pairs and we'll send you out a 4-pack exchange of the new size!
