Period Underwear That Feels Like Your Favourite Pants
Pads that shift, the worry about leaks at night, that damp feeling by the afternoon: periods are hard enough already. This soft, seamless high-waist brief has 4 built-in layers that take in your flow, so you can wear it on its own, day or night, and simply wash it afterwards.

In everyday use
Discreet under clothes, comfy all day
Only the absorbent part has extra layers. The rest is as thin as ordinary underwear, so it does not show under clothes.

Measure your waist and hips and pick the size that matches. Most women find it fits true to size, so you can usually stay with your normal size. If you are between two sizes, choose the larger one. The model in the photos is 180 cm (5 ft 11 in) tall and wears size 2XL.

Seamless hugger
A high waist that stays put
The high waist and full back hug your body smoothly, without digging in. The seamless finish lies flat under leggings, jeans and dresses, so nobody needs to know what you are wearing.
Because only the gusset has extra layers, it feels light and flexible. Most women hardly notice the thickness while wearing it.
4 layers of leak protection
What is inside the gusset

Heavy flow
Made for your heavier days
This brief has the highest absorbency of the range, made for heavy flow days. You can wear it for up to 12 hours, depending on how heavy your flow is.
It does not feel wet against your skin, because the layers take in the moisture. Thanks to the antibacterial outer layer, unwanted odours are neutralised and it stays fresh through the day.
- Day and night: worry-free through school, work and sleep.
- On its own: no pad or liner needed.
- Reusable: wash it and wear it again, period after period.
Easy care
How to wash it
1. Rinse
Rinse the underwear in cold water after wearing.
2. Machine wash
Put it in a laundry bag and wash at 30°C with a mild detergent.
3. Hang to dry
Let it air dry. Do not use bleach or fabric softener.

A greener choice
Wash, wear, repeat
Washable, reusable period underwear means far fewer disposable pads and tampons in the bin, month after month.
We suggest one pair for the day and one for the night. With at least 4 pairs you always have a clean pair ready while the others are being washed.
Questions people ask
Is it hygienic?
Yes. The antibacterial layer helps get rid of bacteria and neutralise odours, so the underwear stays clean and fresh while you wear it.
How long can I wear it?
Up to 12 hours, depending on how heavy your flow is. This brief has the highest absorbency of the range, for heavy flow.
Will it smell?
No. The antibacterial layer neutralises unwanted odours, so it stays fresh through the day.
Does it feel wet?
No. The 4 layers take in the moisture, so it does not feel wet against your skin.
Does it feel bulky?
Most women do not notice it. Only the absorbent area has extra layers, so that part is slightly thicker, but not in a way you see or feel. The rest is as thin as ordinary underwear.
How many pairs do I need?
One for the day and one for the night. At least 4 pairs is best, so you always have clean ones while you wash the others.
How do I choose my size?
Use the size table above with your waist and hip measurements. Most women stay with their usual size. Between two sizes, choose the larger one.
