During your period, your stomach is often bloated and swollen. With high-waisted period swimwear, you can easily conceal the curves of your stomach during your period.
The Naya period swim bottoms absorb your menstrual flow for 8 hours thanks to their absorbent technology.
Their absorbency capacity is equivalent to 3 tampons.
They are designed for light to moderate flows.
The benefits of the Naya high-waisted period swim bottoms:
0 swelling
0 odor
0 leaks
0 stains
8h of absorption
For optimal protection, choose your usual swimsuit size.
Check the size guide to make sure the swimsuit fits properly, neither too loose nor too tight.
The Naya period swim bottoms, with their high waist, are very full coverage. This style comes in black for maximum discretion and a more streamlined silhouette.
The high-waisted Naya period swim bottoms are sold separately.
You can also buy the Lya bikini top that pairs perfectly with the bottoms.

Sustainability
Disposable pads, panty liners, and tampons are among the leading sources of plastic pollution worldwide.
During our reproductive years, we each use between 10,000 and 15,000 of these disposable products.
Sustainable alternatives like period underwear and period swimwear completely replace these disposables. They help reduce the environmental impact of disposable products.
Care guide
Sorio reusable period products are washed in three simple steps:
1. Rinse in cold water until no more blood comes out. If there are stains, you can use a mild soap.
2. Machine wash on a delicate cycle (max 30°C / 86°F).
3. Air dry if possible.
Tip: Don't use a dryer, fabric softener, or bleach. They would reduce effectiveness and shorten the product's life.

How does it work?
The honeycomb layer
Keeps you feeling dry. This honeycomb layer lets blood pass through to the layers below. It is also hypoallergenic and antibacterial.
The absorbent fabric
A technical absorbent layer that captures and channels blood. Offers high absorption capacity.
Flowlock™ reinforced waterproof membrane
Keeps water and blood from mixing. This protection is leakproof. Blood stays trapped in the swimwear and water can't get in.

Perfect size, the fabric and protection are top-notch. I spent hours swimming and at the beach with no leaks and no feeling of being wet. The swimsuit doesn't balloon. Perfect, I recommend it!

Very fast shipping, I received my swim bottoms in just a few days. The size matches the size guide and the fabric is exceptional, it really looks like regular swimwear. So far I'm very satisfied.
Würde es jederzeit wieder kaufen. Kann es jedem empfehlen. 4 Tage im Urlaub getragen und wirklich sehr zufrieden. Am Anfang war ich misstrauisch hatte Angst das es ausläuft aber nein wie beschrieben hält super.
Mes filles sont ravies de pouvoir profiter des baignades n'importe quand. Les maillots ont fait le boulot. Petit bémol : des bouloches sont apparues lors des glissades sur les toboggans.
The size guide is just above the size selector, with exact measurements for each style.
How much can it absorb?
Our swimwear absorbs the equivalent of 3 to 4 tampons, depending on the absorption level you choose, and protects you for 8 hours.
And if you don't know your flow, our calculation guide helps you figure it out in one cycle.
Does it absorb water and balloon in the pool?
No. That's the key difference from regular period underwear.
The waterproof layer forms a barrier between blood and the water outside: flow stays inside, water stays out. The crotch doesn't balloon or get heavy, even after a long swim.
Can people tell it's period swimwear?
No. The absorption technology is built into the fabric and is only a few millimeters thick.
No diaper effect, no visible bulk: from the outside, it looks like any other swimwear.
How do I care for it?
Rinse it in cold water after each use until the water runs clear, then machine wash it at 30°C (86°F) max, in a laundry bag.
No dryer, no fabric softener, no iron: they would damage the absorption technology. Air dry. Everything is explained in our care guide.
How long does it last?
Several years with proper care. The fabrics are anti-chlorine and UV-protective to stand up to both the pool and the sun.
We recommend having at least two, so you can rotate them and let each one dry completely.
What are the shipping times and return terms?
Orders placed before 12 p.m. ship the same business day. Free shipping on orders over €49.
