Why Anti-Leak

Backup protection.
Built into your underwear.

Four reasons ostomates pick Anti-Leak for post-op nights and high-risk days.

200 ml absorbent gusset

4-layer leakproof core captures up to 200 ml — equivalent to a full ileostomy pouch. Wicks moisture away from the skin and locks it in.

Hidden inner pocket

Holds the ostomy pouch flat against the body — even under fitted clothing. No outline, no shifting, no embarrassing slip.

Post-op & menstrual ready

Stoma nurses recommend Anti-Leak for the first 4–6 weeks after stoma surgery. Doubles as period underwear on light to medium flow days.

Antibacterial silver-thread

Silver-thread antibacterial layer suppresses odour. Soft, breathable, machine-washable — built to last 12+ months of daily wear.

How it works

4 layers. Zero leaks.

Wear like normal underwear. The 4-layer absorbent gusset does the rest.

Layer 1

Wicking layer

Skin-touch fabric pulls moisture away from the body and channels it down into the absorbent core — keeps the skin dry.

Layer 2 & 3

Antibacterial absorbent core

Silver-thread antibacterial layer + high-capacity absorbent core lock in up to 200 ml of liquid without odour or seepage.

Layer 4

Waterproof membrane

Outer waterproof layer prevents any seepage to clothing, sheets or skin. The pouch leaks — but you stay dry.

More than panties

Backup protection.
Built into your underwear.

4-layer leakproof gusset + hidden inner pocket + antibacterial silver-thread = peace of mind during post-op recovery, menstruation, and any high-risk day or night.

200 ml capacity

Catch leaks before they reach your clothes.

The 4-layer gusset captures up to 200 ml — equivalent to a full ileostomy pouch. Wicks moisture away from skin, locks it inside, prevents any seepage to clothing, sheets or skin.

Anti-Leak panties for post-op recovery
Post-op recovery

Sleep without watching the clock.

The first 4–6 weeks after stoma surgery are when overnight leaks happen most. Anti-Leak gives you peace of mind so you can actually rest.

Anti-Leak panties for menstrual flow
Period-ready

One garment. Two body experiences.

The same 4-layer gusset that captures pouch leaks handles menstrual flow on light to medium days. No more juggling tampons, pads and pouch management.

Hidden pouch pocket

Discreet outside. Engineered inside.

The hidden inner pocket holds your ostomy bag flat against the abdomen — even under fitted dresses, jeans, structured suits. From the outside: a sophisticated black panty. Inside: a 4-layer leakproof shield + ostomy pouch holder.

Saved my first month post-op

"My ileostomy was new and leaks were happening every other night. Anti-Leak panties caught a 150 ml leak last week — pyjamas dry, sheets dry, sanity intact. Wish I had them from day one."

Sarah M. · USA · 3 months ago SIIL Store
★★★★★

Period + ostomy in one panty

"Game-changer for me. I have an ileostomy AND I menstruate. Anti-Leak handles both. No more tampon-pad-pouch juggle every period. Bought 5 pairs after the first wash."

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

Finally sleep without checking

"I used to wake every 2–3 hours to check the pouch. Now I wear Anti-Leak and sleep 7 hours straight. Even when I had a baseplate failure, the panty caught it. Worth every penny."

Linda P. · Spain · 4 months ago SIIL Store
★★★★★

Confidence on a long flight

"Ten-hour flight to see family. Pre-Anti-Leak I would've been terrified of an in-seat leak. With the panty as backup I just enjoyed the flight. Pouch held — but I had insurance."

Maria S. · Italy · 5 weeks ago Amazon
★★★★★

No odour, no smell, even after a leak

"The silver-thread layer really works. Had a small leak overnight, got up, rinsed the panty in cold water, washed normally — zero smell after. Better than expected."

Sophie D. · France · 6 months ago Amazon
★★★★★

Stoma nurse recommended these

"My stoma nurse insisted I wear Anti-Leak for the first 6 weeks post-op. She was right. Caught two overnight leaks in week 2 when my pouch fit wasn't dialled in yet. Thank you SIIL."

FAQ

Everything you want to know

How much liquid does the gusset absorb?
Up to 200 ml — equivalent to roughly one full ileostomy pouch. The 4-layer absorbent core has a waterproof outer membrane that prevents any seepage to clothing, sheets or skin. This works for both pouch leaks and menstrual flow on light to medium days.
Should I wear Anti-Leak post-op?
Yes — many stoma nurses recommend wearing Anti-Leak panties for the first 4–6 weeks after stoma surgery. The high-waist band sits above the surgical site without rubbing, the soft antibacterial knit is gentle on healing skin, and the absorbent gusset gives you peace of mind through the night when leaks are most disruptive.
Do they double as period underwear?
Yes — the same 4-layer gusset works for menstrual flow on light to medium days. For heavy flow, layer with a tampon or menstrual cup; the panty acts as backup protection against unexpected leaks. One garment for two body experiences (ostomy + period).
How do I wash Anti-Leak?
Rinse in cold water immediately after wear (this preserves the absorbent core's capacity). Then machine-wash at 30 °C on a gentle cycle, inside out, with similar dark colours. Air-dry flat — do NOT tumble-dry (heat damages the waterproof membrane). Avoid bleach and fabric softener. With normal care, one pair lasts 12+ months.
Will the gusset feel bulky or uncomfortable?
No — the 4 layers are slim (about 4 mm total) and integrated seamlessly. Most customers report forgetting they're wearing them. The fabric is soft, breathable, antibacterial silver-thread; the gusset shape contours to the body without bunching or rubbing.
How do I pick the right size?
Measure your natural waist (the narrowest part above your belly button) and your hip at the widest point. Use the size guide above the Add-to-cart button. Between sizes? Choose the larger — the soft knit adapts down 4 cm comfortably. We accept exchanges within 30 days.
Will Anti-Leak fit my ostomy pouch?
Yes — the hidden inner pocket is sized to fit one-piece and two-piece pouches from Coloplast, Hollister, ConvaTec, B. Braun, Pelican, NuHope, Marlen and Welland. The pocket fabric is stretch elastic so it adapts to different pouch shapes and capacities — ileostomy, colostomy and urostomy.
What if Anti-Leak doesn't work for me?
30-day no-questions-asked returns. If the size or fabric isn't right, email hola@siilostomy.com and we'll refund or exchange. Used items are accepted for hygiene-relevant ostomy underwear — we re-process all returns through our medical-grade hygiene protocol.
