A Beginner’s Guide to Period Proof Underwear

What is period proof underwear?

The answer to all your prayers. Welcome to the low maintenance period revolution. Period proof underwear have an absorbent core made of 3D textile technology that absorbs your period. Four whole tampons worth. And they last for ten hours. Sold? Get them here.

Do they leak?

Nope, no leaks, leak-proof, leaf-free. Hello white sheets. nüdie Organic Period Pants are absorbent enough for 4 tampons to keep us, and our clothes, all protected.

How do I know when I need to change my period proof underwear & how often do I need to change them?

This varies massively for different types of period proof underwear, but for nüdie Organic Period Pants the answer is all about your flow. They are absorbent enough for 4 tampons, but if you are on the heavier side you might have to change them a bit more frequently.

But don’t they feel wet and sticky? Aren’t they messy? Do they smell?

If you were to wear period proof underwear for far too long they might feel a bit sticky, but they are made from super moisture-wicking organic cotton that keeps you feeling dry, secure, and never smelly.

So they are 100% hygienic?

100%! Period blood is pretty hygienic anyway. The idea that period blood is dirty is definitely one of our top five least favourite myths. As long as you wash your period proof underwear as you would normal underwear all will be well.

Why should I choose reusable period products?

The environment nüdie Organic Period Pants help you save the planet & your wallet- just imagine no disposable or compostable period products for 3-4 years. That sounds like a trip to Paris to me.

How do I pick the right absorbency?

The heavier your flow the higher the absorbancy you need. Here at &SISTERS we like to keep things simple, so we made period proof underwear that absorbs 4 tampons- so you don’t have to worry about buying too low an absorbency. We got you all covered. The other thing to consider is that heavier bleeding usually means you bleed to the front and back of the pants as well. So, it is important you have full coverage. Don’t worry we’ve got that too!

How long do they last?

100 washes, or approximately 3-4 years worth of period proof underwear heaven.

How many pairs do I need?

This depends on your flow, the length of your period & if you are just wanting to use period pants or use them alongside other things. nüdie Organic Period Pants can be worn for up to 10 hours and typically take around a day to dry, so for someone with a three day medium flow period you probably need four pairs if you are only going to wear period pants. If you only plan to use them at night, on the other hand, you probably only need two pairs.

Can I sleep in them? 

Yes they are perfect for sleeping. Period proof underwear keeps you feeling nice and secure without the risk of leaks- no matter how much you wriggle.

Can I exercise in them?

Are they good for teens or tweens?

Teens & tweens absolutely rave about nüdie Organic Period Pants. They are perfect for long school days when algebra and who Barney is going out with now is much more important than menstruating. Periods are a nuisance at that age & nüdie Organic Period Pants keep them nice and low maintenance. Get nüdies for your fave teens & tweens.

What about when I am out or at work?

Usually you can just pop period proof underwear on in the morning and not worry about it all day. Keep your eyes on the big presentation or focus on keeping the prosecco coming at bottomless brunch. If your flow is on the heavier side, you may have to change when you are out and about. We recommend folding your used period pants so that they inside are folded inwards and then just pop them in a bag to wash later. 

How do I wash them?

Rinse with cold water if you can, then pop them in the washing machine with everything else. 40 degrees, no fabric conditioner, no bleaching agents. Blood breaks down quite easily in washing machines and we make our period pants black so you don’t have to worry about stains.

Can I tumble dry them?

Every time you use the tumble dryer your period proof underwear will reduce in absorbency as the dryer damages the absorbent core. If you want your pants to last as long as possible avoid.
