FAQs about Period Underwear

Think of them as your super comfy, leak proof besties. Featuring patented absorbent and odour resistant technology, Hello Undies will keep you feeling dry and secure all day long. And the best part? They can be used again and again - making them great for your wallet, and the environment.

How much liquid can period underwear hold?

Most period underwear will hold between 1-4 tampons worth of flow (15-20 ml)

Our Hello Undies can absorb as much as 5 tampons or pads. Our absorbent underwear is comfortable and reliable giving you the peace of mind you need at work or school. They are also great for overnight - giving you uninterrupted sleep thanks to their maximum absorbency protection.

How do I choose the right size of period undies?

Choosing the right size of period underwear is essential to ensuring comfort and effectiveness. Here are some tips to find the perfect fit.

  1. Measure Your Waist and Hips: Start by measuring your waist (at your belly button level) and your hips (the widest part).
  2. Refer to Size Charts: Most period underwear brands provide size charts on their website to check and find your measurements.

Our Hello Undies sizing is based on international standards but we recommend relying on your actual measurements for the perfect fit.

Can period underwear replace pads and tampons?

Yes, absolutely. You can rock your period undies on their own or team them up with a menstrual cup or menstrual disc. You're the expert on your body and flow, so mix and match whatever feels right for you. Your comfort, your rules.

How do I wash and care for period underwear?

There are 4 steps to wash your period undies:

  1. Before washing, it is recommended to rinse the underwear under cold water. This helps to prevent stains. 
  2. If stains or odour have set in, try gently scrubbing the gusset and other areas with a soft brush and mild detergent.
  3. Turn the underwear inside out and put it in the washing machine. Follow the manufacturer’s instructions but most will suggest using a delicate setting, cold water, and mild detergent.
  4. After washing, hang the underwear to dry and avoid using the dryer.

How long do menstrual undies last?

The lifespan of menstrual underwear for women can depend on a number of factors, like:

  • Do you often use them?
  • How well do you take care of them?

Typically, they can last anywhere from 6 months to over 1 year.

However, you will be amazed because Hello Undies can last at least 2 years. Hello Undies are made of 78% polyamide and 22% elastane on the outer layer and 97% polyester and 3% elastic on the inner absorbent layer. These materials ensure durability over time, which saves you a lot of money and reduces waste in the environment.

Is period underwear comfortable to wear?

Period underwear is an alternative to traditional single-use pads and tampons. They are discreet under clothes, and they are comfortable and gentle on the skin. You can wear any clothes you want without worrying about leaks, and you can even wear them at the gym while sleeping, at work, or at school.

Hello Undies are independently lab-tested and free of harmful substances such as PFOS, PFOA, AZO dyes, and organic compounds. They have Okeo-Tex Standard 100 accreditation and are made from hypoallergenic materials that ensure lower PH levels that are kind to your skin, making you feel comfortable.

Can I wear menstrual undies overnight?

Absolutely! You can wear your period pants at night without any hesitation. Some individuals may be concerned that period panties do not provide enough protection or absorbency to handle an entire night's flow. However, modern-day period pants utilize advanced multi-layer technologies that are specifically engineered to manage heavy overnight flows.

Is good underwear for periods suitable for wearing at the gym?

Yes, period undies are much more reliable and less bulky than wearing a pad at the gym. They are discrete and cannot be seen when you are wearing exercise gear.  Period undies are designed to absorb menstrual flow and come in different absorbances. They are good for light incontinence too. 

Is period underwear eco-friendly?

Period underwear is a great sustainable alternative to disposable pads or tampons. It is reusable which will save you money and eliminate the need to use single-use options that create waste and are expensive over time compared to reusable period care options. Furthermore, organic period underwear is often made from microfiber fabrics such as organic cotton and bamboo viscose. Therefore, it contributes to environmental protection.

Hello Undies are reusable, and each pair will last at least two years, while single-use pads and tampons can take more than 500 years to biodegrade.
