Flow 4 normal waist, heavy flow
We've got you <3 The long-awaited Flow 4.
Flow 4 is your softest new shorts for a heavy flow. Also, it's our very first product made in Portugal.
The shorts are designed with a cute little leg that is cut diagonally on the thigh to give the most flattering look. On the front and back, you'll see our curved signature seams, just like on Flow 1, which accentuate your curves and make the underwear something more than just a basic pair.
The underwear's absorbency is for heavy flow—wonderfully soft for the night, postpartum or just for those days when you need a little more coverage on your bum or a greater absorbency.
Machine washable
Good for nighttime

For heavy flow
Flow 4 is made for heavy flow.
But do you actually know how much you bleed? We rarely do (unless you're an experienced cup user), as even a tiny bit of blood can look like a lot in the toilet.
Heavy flow, in our terms, corresponds to 2-3 regular tampons, approximately 10-15 mL of blood.
If you experience very heavy bleeding, with a need to change pads every hour or so, we recommend combining your period underwear with a disc or cup.
Material
Outer:
95% organic cotton - 5% elastane
Technical layers:
Top layer: 70% cotton - 30% PLA
Middle layer: 44% Modal - 39% cotton - 17% Lyocell
Membrane: 100% polyamide
Washing guide
Use them, rinse them in cold water, and wash them at 30 or 40 degrees together with the rest of your clothes.
The detergents we have today are super effective, so you can easily clean the underwear at low temperatures. Avoid using the tumble dryer! It's not good for the environment, and the absorbent layer will lose its absorbency more quickly. Avoid using fabric softener as the absorbency will deteriorate even faster.

Frequently asked questions
As a starting point, you must choose your normal size. We strive to continuously streamline the collection, although the materials may work slightly differently.
Make sure the panties fit relatively close to the hip, as they need to be able to hold the blood.
Remember; you can always exchange as long as you try your Flows with your own panties underneath.
Our panties have different absorbency, but this is described under each style, indicated by drops. We continue to work on expanding the range.
If you bleed heavily, you can use a menstrual cup or disc together with our menstrual panties.
The top layer at the bottom of the panty is woven so that the blood is directed down into the panty, and this keeps your skin dry.
The middle layer is woven like a towel so that it holds the blood (or other fluids, e.g. urine).
And at the bottom is a polyamide membrane that ensures that you don't bleed through.
When the top layer starts to feel wet or you can see blood at the edge of the panties, they are ready to be changed.
- First, rinse your panties in cold water until the water runs reasonably clear.
(If you don't want to wash them right away, hang them to air dry inside out) - When you are ready to wash, wash them at 40 degrees with similar colors.
(We have specially developed a detergent that can also remove odors) - Hang them to air dry inside out - and they are ready for the next bleeding.
(Avoid dryers. It is not good for the environment and the absorbent layer will lose its absorbency faster)
It depends both on how often you wash clothes - and how much you bleed.
The more you bleed, the more often you need to change your panties. Most people switch morning and evening - and with heavier bleeding, e.g. day 2-3, an extra time in the afternoon. Think of it as changing roughly as often as a pad.
On that level, a start could be 3 pairs (you always get 10% on 3-4 pairs). Then you can test how the day goes.
But the more pairs, the easier and more comfortable the experience. We have customers who have 10-12 pairs in their drawer. And you always get 15% on 5 pairs or more.
... Pssst... Your panties are suitable for "all bodily fluids"; after sex, after a good laugh, during menstruation.
It's kind of a silly word, "leak". It sounds like an engine dripping.
We have a body that bleeds - sometimes the blood has its own ways. And that means bleeding through or leaking.
But of course we understand the word. And yes, they are leak-proof, provided they are used for what they can handle.
If you experience 'leakage', you will experience bleeding to the sides rather than through, as the membrane will prevent permeation.
You will find the absorbency of each style on each product page.
The key to getting them properly clean is the cold water they are rinsed in before washing. You may also know this from blood stains on the clothes.
Cold water breaks the surface tension of the blood, and this means that the washing machine can easily wash them clean afterwards.
A combination of the cold water, 40 degree washing and the super effective detergents we have today means that the panties get clean.
The Consumer Council Tænk recommends the same washing order and says it is good for hygiene.
You describe them as *game changing*.
All menstrual products have their advantages and disadvantages. But the big advantages of menstrual panties are that you can bleed freely. And it's surprisingly nice! You must not get anything into your body that can disturb the natural balance of the vagina or risk TSS (Toxic Shock Syndrome).
And they also stay seated around the seagull, and this provides a great sense of security, especially at night - unlike bandages, which can curl up, pinch and cause rashes.
