Period Flow Bikini - Johanne
✓ Comes in sizes 140-176
✓ Quick-drying swimwear
✓ One-shoulder top
Johanne Bikini is our first period swimwear for tweens and teens.
According to an Australian study, 67.3% of young teens and tweens skip swimming when they have their period. With Johanne Bikini you can continue swimming without worries.
The bottom looks like a regular swimsuit but with three unique layers sewn in, it is ready to absorb and hug you, whether you are in the water or relaxing by the pool.
If you are bleeding heavily, we recommend that you combine your bikini with a disc or cup.
Menstrual swimwear, like Flow menstrual panties, is sewn with a built-in pad, consisting of a minimum of 3 technical layers that direct fluid into the pad, absorb the fluid and ensure that you do not bleed or leak through.

Frequently asked questions
Please wear your regular size in your swimwear.
The absorbency is light to moderate. If you are bleeding heavily, we suggest combining it with a cup or a pad.
Our swimwear is designed with a built-in, absorbent layer that captures and encapsulates menstrual blood. This layer is combined with a waterproof yet breathable membrane that prevents you from bleeding through while swimming or sunbathing.
The textiles are light and quick-drying, ensuring that you can move freely and feel dry shortly after being in the water.
1. If you have bled in your menstrual swimwear, rinse them in cold water until it runs clear.
2. Protect your swimwear in a laundry bag and wash your panties with similar colors at 30-40 degrees.
Tip: You can wash with our Allergy Certified special detergent Bloody Clean .
3. Dry them inside out on a clothesline - and you're good to go again.

Can teens bathe during menstruation?
An Australian study shows that 67.3% of teens avoid swimming during their period. We want to change that.
Of course, you can bathe during your period - some will even experience relief from discomfort when moving in water.
Menstrual swimwear makes it possible to swim safely during menstruation - the same technical layer as in your panties, but quick-drying.
