Why this bikini
Holiday colour.
Holiday colour.
Pouch-flat security.
A waist knot, patterned fabric and an inner pocket in high-waisted swim bottoms.
Multicolour print masks outlines
Terracotta, sand and small blue dots bring Summer’s print to life. The print adds visual detail over the pouch area and helps soften its outline. The inner pocket holds the pouch inside the garment.
Signature waist-knot detail
The gathered fabric and knot at the front waist add fabric detail over the pouch area to help soften its outline.
Inner pouch pocket
The inner pocket holds the pouch close to the abdomen, keeping it close to the body and helping soften its outline beneath clothing.
Anti-leak, anti-pancaking, fast-dry
The reinforced waistband sits above the stoma and locks the pouch in place. Engineered swim fabric dries in minutes, survives chlorine, salt and full sun.
How it works
Three steps. Beach-ready.
See how to put it on and take a moment to check the fit.
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 behind the multicolour print.
Step 3
Knot & walk in
The waist-knot sits flatteringly at centre-front. Pair with your favourite bikini top and step poolside — swim, sunbathe, paddle.

Waist-knot detail
A flattering focal point.

Proven protection
Anti-leak. Anti-pancaking.
The inner pocket holds your pouch inside the garment. Before getting into the water, check that its position and fit feel comfortable.
Pool, sea, sun
Fast-dry, chlorine & salt safe.
Engineered swim fabric dries in minutes, survives pool chlorine and ocean salt, keeps the print vibrant under full sun. Rinse, line-dry, repeat all summer long.

The print is a brilliant disguise
"I'd been buying solid-coloured ostomy swimsuits and the pouch outline always showed through wet fabric. With Summer's multicolour print, even when wet, you can't see anything. Total game-changer."
★★★★★
Holiday-feeling colours
"Took it to Mallorca. The terracotta and sand colours photographed beautifully — every beach photo looks intentional, not 'medical swimsuit'. Got compliments at the resort. The waist-knot is super flattering too."
★★★★★
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."
★★★★★
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 paired it with the Bikini Top Green."
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.
Is it sold with a top, or just the bottom?
Just the bottom. The Summer pairs with our Bikini Top Green or any standard bikini top in your wardrobe. Terracotta, sand, navy, white or mustard tops all pair beautifully with the multicolour print. Top sold separately so you can mix & match colours.
How does the multicolour print help with the pouch?
Busy, high-contrast prints disguise outlines far better than solid colours. The Summer's Mauritius-sand palette (warm terracotta, sand, blue dots) is visually busy enough to mask any pouch outline through wet fabric while still photographing beautifully on a bright beach.
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 [email protected] and we'll refund or exchange.
