    FAQ

    How does Leakproof period underwear work?

    Our leakproof period panties feature triple-layer technology. The inner layers absorb menstrual flow or light bladder leaks, while the leak-resistant outer layer helps protect clothing and bedding from stains.

    What do the different absorbency levels mean?

    Most of our Leakproof period underwear can absorb 2-6 regular tampons worth, which is about 15-40 ml of liquid. 1 regular tampon absorbency equals 6 ml.

    Light absorbency

    Great for light period days or when you're expecting your period. Absorbs approximately 12 ml, or the equivalent of 2 regular tampons worth of liquid.

    Medium absorbency

    For those with light to medium flow. If you have a heavier flow, wear it with a backup like a pad or tampon. Absorbs approximately 24 ml or the equivalent of 4 tampons worth of liquid.

    Heavy absorbency

    For those with medium flow. Absorbs approximately 30 ml or the equivalent of 5 tampons worth of liquid.

    Super absorbency

    Ideal for those with heavy flow, these can replace other products for both day and night use. Absorbs approximately 40 ml or the equivalent of 6-7 tampons worth of liquid.

    What is the difference between Period Underwear and Regular Underwear?

    Even if it looks like your regular undies, our Leakproof Period Underwear features a patented gusset with a leakproof layer and can absorb between 2 to 7 tampons worth of liquid, providing you with confident protection against period leaks, and light bladder leaks.

    Our EiVi Cotton Underwear features a double layer gusset with pockets to hide pad wings, but they do not provide any leakproof protection.

    Which of your models are best for sleeping?

    It depends on your preferred sleeping position.

    If you primarily sleep on your back, we recommend choosing panties with an extended back gusset, such as our Leakproof Hi-waist and Leakproof Boyshorts.

    If you prefer sleeping on your stomach, we suggest opting for Leakproof Boyshorts. However, the front gusset of our Leakproof Hi-waist panties extends quite high in the front, so if you prefer that model, you can also wear them for a comfortable night's sleep.

    Are your Leakproof period underwear good for light bladder leaks?

    Yes! Women like wearing our undies to prevent light bladder leaks.

    They absorb up to 25 ml of liquid and feature anti-odour properties.

    What is TENCEL™ Modal fabric?

    TENCEL™ Modal is super soft, eco-friendly fabric made from regenerative plants, produced using less water and fewer chemicals. This fabric is originated from Austria.

    How long are the gussets in period underwear?

    Depending on the size and style of underwear, the leakproof gusset ranges from around 15 cm – 22cm in the front, and 37cm to 44 cm overall. Some models have extended gusset up to the waistline both - in the front and in the back, and some have shorter gusset in the front. Please see the product pictures, and our icons, which explain where extended gusset is.

    Do I need to wear a pad or tampon with period underwear?

    The absorbency level of our Leakproof period underwear, as well as the heaviness of your menstrual flow, will determine whether you can wear our panties on their own or as backup protection alongside a menstrual cup, pad, or tampon. Our leakproof panties are unique because you can wear the pad while tucking in the wings in the gusset pockets, thereby preventing leaks and discreetly hiding the wings.

    How do I wash Leakproof period underwear?

    Washing your period underwear is a simple process. We have designed our products to be effortless to wash and care for. If you prefer, you can rinse your stained panties in cold water, and for optimal results, machine wash them on a cold cycle using mild detergent. Finally, tumble dry on low heat or hang to dry. Don't use softener or bleach, and never machine dry or iron.

    What period underwear model should I choose?

    Our customers have played an integral role in the development of every style of period underwear that we offer. The best style for you is the one that suits your needs and preferences. When selecting period panties, approach it just like you would with regular underwear. The only additional consideration is the protection level.
