Why this bikini

Made for waves,
walks and warm sand.

Four reasons our high-waisted ostomy bikini outperforms regular swimwear.

Inner pouch pocket

Stoma-level inner pocket holds your ostomy pouch flat against the body — no shifting, no sloshing, no visible outline through the fabric.

Anti-leak & anti-pancaking

The high-waisted, reinforced waistband sits above the stoma and locks the pouch in place — no leaks during a swim and no "pancaking" that stops drainage.

Looks like normal swimwear

High-waisted silhouette with a soft daisy print. Pairs with any bikini top — no medical aesthetic, just confident poolside style.

Fast-dry, chlorine & salt safe

Engineered swim fabric dries in minutes after a dip. Survives pool chlorine, ocean salt and full sun. Rinse, line-dry, repeat all summer.

How it works

Three steps. Beach-ready.

Slip it on. Tuck the pouch. Walk in.

Step 1

Slip it on

Step into the bikini bottom and pull it up to the natural high waist — above your stoma. The waistband sits firm and supportive.

Step 2

Tuck the pouch

Place your ostomy pouch inside the inner pocket. The pocket holds it flat against the body — invisible from the outside.

Step 3

Walk in

Pair with your favourite bikini top and step poolside. Swim, sunbathe, paddle — the bottom holds the pouch through every move.

More than swimwear

Beach-ready confidence,
every splash.

Engineered for ileostomy, colostomy and urostomy. The inner pocket and high waistband keep the pouch flat through swim, sun, sand and play.

Inner pocket

Pouch invisible. Stays flat.

The dedicated stoma-level inner pocket holds your ostomy pouch flat against the body — no shifting mid-swim, no visible outline through wet fabric, no awkward bulge.

Proven protection

Anti-leak. Anti-pancaking.

The reinforced waistband and inner pocket keep the pouch flat — customers report swimming, snorkelling and paddle-boarding without a single leak.

Pool, sea, sun

Fast-dry, chlorine & salt safe.

Engineered swim fabric dries in minutes, survives pool chlorine and ocean salt, and keeps its shape under full sun. Rinse, line-dry, repeat all summer long.

First swim in three years

"I hadn't worn a bikini since my surgery. The Celeste sits high above the stoma, the pouch goes flat in the inner pocket, and I just walked into the sea. Cried a bit. Worth every penny."

Sarah M. · USA · 3 months ago Amazon

Looks like a regular high-waisted bikini

"Took it on holiday to Greece. Nobody at the pool guessed. Daisy print is gorgeous, the high waist is flattering, and the inner pocket means zero pouch outline even when wet."

Anna K. · UK · 6 weeks ago SIIL Store
★★★★★

No leaks, no pancaking, full swims

"Swam laps for an hour, snorkelled, walked the beach. The pouch stayed flat the whole time and drained normally afterwards. The high waist holds everything in place."

Linda P. · Spain · 2 months ago SIIL Store

Fits my Coloplast pouch perfectly

"Was worried about my SenSura Mio fitting in the pocket — it slips in easily and stays flat. Fabric dries in minutes after a swim. Already ordered a second one."

FAQ

Everything you want to know

How do I pick the right size?
Measure your waist (in cm) at the level of your stoma. Use the size guide above the Add to cart button. Between sizes? Choose the larger — the high waistband adapts comfortably and you'll appreciate the extra coverage above the stoma. We accept exchanges within 30 days if the size isn't right.
Will it fit my ostomy pouch brand?
Yes. The inner pocket fits drainable, mini and two-piece pouches from Coloplast, Hollister, ConvaTec, B. Braun, Pelican, NuHope, Marlen and Welland. The stretch fabric adapts to pouch shape and volume during a swim.
Is it sold with a top, or just the bottom?
Just the bottom. The Celeste pairs with our Bikini Top Green or any standard bikini top in your wardrobe. Selling the bottom alone keeps the price down and lets you mix & match colours.
Can I swim in chlorine and salt water?
Yes. The fabric is engineered for both pool chlorine and ocean salt. Rinse with fresh water after every swim and air-dry in the shade — that simple care routine keeps the elastic and print fresh for multiple seasons.
Will the inner pocket stop my pouch from "pancaking"?
Yes — the high waistband and reinforced inner pocket help keep the pouch flat against the body, which dramatically reduces the pancaking effect (where the pouch flattens and stops draining). Customers report normal pouch drainage even during long swims.
What if it doesn't work for me?
30-day no-questions-asked returns. If the size or fit isn't right, email hola@siilostomy.com and we'll refund or exchange.
