We have worked intensively with our manufacturing partner in China to develop and produce the best possible period panties. The manufacturer is socially and environmentally certified, works with certified recycled materials, and is very experienced in working with the technology behind period panties.

All our period panties are lab tested on absorbency by the Research Institute of Sweden (Rise).

Our Period-Proof Cheeky can hold up to 15ml (≈ 3 tampons), the Lace Highwaist Brief can hold 25ml (≈ 5 tampons) and the Micro Highwaist Briefs can hold 35ml of menstrual liquid (≈7 tampons).

Everybody’s flow is unique and the wear time depends on how much you bleed daily. If you have a light flow, you can easily wear your panties all day without worrying about leakage. The heavier your flow, the more likely it is for you to need a higher absorbency or even change panties during the day. Please see the next question How do I know what absorbency to buy? to understand how each panty absorbency translates into ml/ tampons/ pads/ cups. Using the figures, you can determine which panties suit your needs and how much menstrual liquid they can hold, hence how long they will last you. However, we do not recommend wearing your period panties for longer than a day.

The best way to determine your optimal absorbency level is to look at your personal use of other period products, i.e. how many pads/ tampons/ cups you use per day and in what phase of your period. 

Below is an overview to make finding the right panty quick & easy. From here, you can mix and match absorbencies and styles to suit your flow. 

Low absorbency = 15 ml = 3 tampons = 3 pads = 0.5 cups

Medium absorbency = 25 ml = 5 tampons = 5 pads = 0.8 cups

High absorbency = 35 ml = 7 tampons = 7 pads = 1.2 cups

We recommend going for the size you usually choose for Understatement panties. For finding the best fit of panties, we recommend taking measurements of your waist and hip for panties then clicking the size chart to find out the best size for you

Our period panties is designed to be highly absorbent and feel dry, so you may be unable to tell if it is getting full. To determine when it's time to change, we recommend you pay attention to how long you have been wearing the panties and the heaviness of your flow.

The number of period panties you need depends on your personal flow and also how often you plan to do laundry. But we recommend having at least 3-5 panties with different absorbencies based on your unique flow.

No, you do not need to combine our period panties with other menstrual products, such as pads or tampons. Our period panties are designed to give you full protection.

Yes, you can sleep in our period panties. Our period-proof panties are designed to perfectly hug your curves and give you optimal protection, also during the night.

Period panties, tampons, or pads are all equally effective to use during your menstruation. Your monthly cycle can leave you feeling vulnerable, in pain, or insecure - so we believe it’s important to use what personally provides you with the most comfort and confidence. However, period panties are a great eco-friendly choice compared to one-time-use products, such as tampons or pads. They last you just as long as any regular panties would which gives them an important environmental advantage. While tampons in rare cases can be associated with Toxic Shock Syndrome (TSS), there have not been any reported cases of TSS in association with the use of period panties. 

Our period panties were developed and tested to absorb menstrual liquid, so we can not guarantee protection from urine leakages.

You can use our period panties just as long as any other regular panties. Their absorbency qualities will remain given you wear and care for your period panties as instructed.
