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.
Ciao, ho 45 anni e gli ultimi due anni ho passato i miei viaggi al mare con il ciclo nonostante tutti i conteggi fatti, quest'anno ho deciso di provare questo costume e che dire... Spettacolare... Lo straconsiglio a tutte, giovani e non. Io ho ciclo abbondante e devo dire che mi sono trovata benissimo e non si vede x niente che è un costume diverso, ho fatto di tutto dalle semplici passeggiate a ore di snorkeling.
Compratelo!!!
Ne ho ordinati 2 per mia figlia, che ne aveva già uno di un'altra marca. Quando li ha provati, ha detto che sono decisamente più comodi rispetto agli altri. Non li ha , però, ancora testati in acqua. Solo la spedizione è stata un po' lenta, perciò vi consiglio di fare l'ordine almeno 15/20 giorni prima della partenza.
Todo ha ido bien.
Mi hija ha podido disfrutar del baño en la piscina y mar, sin ningún problema.
Siguiendo las instrucciones de lavado todo ha sido más fácil.
Muy recomendable su compra, especialmente para adolescentes que se enfrentan por primera vez a la regla.

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.
