Period Underwear FAQs

About Asan period underwear

What is period underwear?

Period underwear looks and feels just like your regular underwear - but it’s designed to absorb your period flow. It's made with multiple leak-proof layers, it keeps you dry, comfortable, and protected all day long. You can wear it on its own or as backup with a cup or tampon.

Is the Asan period underwear safe?

Yes, the Asan period underwear is absolutely safe to use!

The Asan Period Underwear is made in accordance with global OEKO-TEX standards to ensure there are no harmful micro-plastics or chemicals. 

OEKO-TEX is a globally recognised system for testing and certifying textiles and leather products for harmful substances, ensuring consumer safety and promoting sustainable production.

What is different about the Asan period underwear?

Unlike other synthetic options available, Asan’s Period Underwear is made with 95% cotton and developed in line with global OEKO-TEX standards. It is designed with leak-proof and odour-free layers to ensure that it is comfortable, breathable and safe for your body and the planet.

What is it made from?

The Asan period underwear body is made from 95% cotton and the gusset is made from four leak-proof and odour-proof absorbent layers.

Is it available in multiple colours?

The Asan period underwear is available in black to be stain-free.

The dark colour naturally hides stains, keeping your underwear looking fresh and lasting longer.

Plus, black pairs beautifully with anything in your wardrobe, making it your go-to for comfort, practicality, and peace of mind during your period.

What style is the Asan period underwear?

We've developed the Asan period underwear in two different styles:

Light/medium flow: Hipster style for a breezy fit to feel just like regular underwear.

Heavy flow: High-waist style for maximum coverage, protection and comfort.

Is it eco-friendly?

Yes. The Asan Period Underwear is made with 95% cotton, which is much better for the environment compared to synthetic options available.

It can be washed and reused for 2-3 years depending on the care. This makes it a very eco-friendly option compared to single-use pads and tampons - one underwear replaces around 500 pads!

Sizing

How many sizes does Asan offer?

The Asan period underwear comes in two sizes: light/medium flow and heavy flow. Your size depends on how often you tend to change tampons or pads on the heaviest days of your period.

  • Light/Medium Period Underwear: For those who change pads/tampons every 6+ hours.
  • Heavy flow Period Underwear: For those who change pads/tampons every 2-6 hours.
What if my flow varies throughout my period?

It is normal for menstrual flow to vary throughout your period. We advise choosing your size based on what you would require for the heaviest day of your period.

For example, if you have heavy flow for the first two days followed by light flow, we advise selecting the heavy flow period underwear.

We’d recommend trying both the light-medium and heavy styles, which is perfect for different days throughout your cycle. 

How much flow does it hold?

The Light/medium flow holds up to 20ml and the Heavy flow holds up to 35ml.

Usage

Can I start using the period underwear before I am on my period?

Yes, you can use your period underwear ahead of getting your period if you are expecting it. This also minimises the stress of having to rush to find tampons or pads once you experience a stain.

How long can I wear my period underwear for?

You can wear it for up to 8-12 hours depending on your flow.

Make sure to change it within 12 hours or if it starts to feel damp.

Can I use the period underwear for exercise?

Yes, absolutely! You can comfortably exercise, dance and play sports while wearing it.

Can I sleep wearing the underwear?

Yes, one of the many benefits of the period underwear is that you can have an undisturbed night’s sleep while wearing it.

The gusset is designed to provide full coverage for your period so you won’t leak even while you move around in your sleep.

Can I use the underwear on its own or do I need back-up protection?

You can absolutely wear it alone. You don’t need another period product as the Asan Period Underwear is super absorbent.

If you are a cup user, the Light/medium flow underwear is a great alternative option to liners for backup to your cup and that extra peace of mind!

Help! The underwear is leaking.

If your underwear is leaking, it's time to change it! Simply put your underwear to wash and use a fresh pair.

Can I use the period underwear for spotting?

Yes absolutely! The period underwear is a great option to manage spotting.

Can I use the period underwear for vaginal discharge?

Yes you can. The odour-free layer will also ensure that your vaginal discharge does not cause a smell.

Can I use the period underwear for incontinence or bladder leaks?

Yes definitely! The Asan period underwear is a comfortable and reliable solution for incontinence or bladder leaks.

Cleaning and care

How do I keep my period underwear clean?

To clean your period underwear, first rinse it in cold water.

Then hand wash or place it in a cold machine wash. Hang to dry.

Can I use regular detergent to wash my underwear?

Yes, you can use regular fabric washing detergent on your period underwear. 

We recommend using the Asan OneDrop cleanser as it is formulated to be gentle and safe. Just squeeze a few drops of it into the gusset, scrub and rinse.

How often should I replace my period underwear?

The Asan Period Underwear is designed to last 2-3 years if maintained well.

You should replace your period underwear if there is any damage to the gusset or fabric.

Your health

Can I use the underwear if I have a yeast or other infection? 

We do not advise using your period underwear while you have a vaginal infection. Please wait for your infection to clear up. However, it is worth noting that because sanitary pads are associated with rashes and itching, the Asan period underwear is a much better long-term option to avoid vaginal infections.

Can I share my period underwear?

We don’t advise sharing your period underwear as it is for personal use.

Can I use the underwear for postpartum bleeding?

Yes absolutely!

Postpartum bleeding refers to the heavy bleeding that is experienced after giving birth. The Heavy flow Asan period underwear is a fantastic option to manage postpartum.

Will the underwear smell? Will I smell while using it?

No, not at all! The Asan period underwear is designed with an odour-free layer to absorb any odour generated by your period. So unlike disposable pads, you won’t be able to smell anything.
