Tired of feeling your bag with every move?

Every step, every laugh, every hug pulls at your stoma. The bag flops, the skin irritates, sleep gets shallow — and over months that pressure builds into a parastomal hernia. 1 in 3 ostomates develop one within two years.

You've tried bigger waistbands, baggy clothes, support belts that bunch up under jeans. Nothing holds the bag flat all day.

SIIL garments hold the weight of your bag and relieve the stress on your skin and abdomen — the way your stoma nurse recommends. Designed by ostomates, tested with every bag brand, worn by 50,000+ across 50 countries.

Your second skin

Be in your body again — without thinking about the bag.

The mirror in the morning. Date night. The hug that lasts a beat longer. SIIL pieces sit like a second skin — soft, secure, invisible — so the bag stops being the thing you think about first.

No more flinching. No more hiding. Your scars, your shape, your favourite people — yours, in full.

Everything about Ostomy Underwear.

The honest answers our community asks every week.

Ostomy underwear is specialised intimate wear engineered to support the pouch, prevent leaks, and reduce parastomal hernia risk. SIIL pieces feature a hidden inner pocket that secures the pouch flat against the body without restricting drainage.

This makes daily life comfortable, work outfits seamless, and intimate moments feel natural again. Whether you have a colostomy, ileostomy or urostomy, SIIL underwear gives you the same garment for office, swim, sport, sleep and date night.

FAQs: Common Ostomy Underwear Questions

The 5 questions every ostomate asks.

No. SIIL pieces are designed and tested to hide every contour of your pouch — even under fitted dresses, white shirts, slim swimwear and date-night lingerie. That's the whole point.

The belt and high-waist pieces give gentle compression at the stoma site. 75% of customers with parastomal hernia risk report no progression after 6 months of daily wear. Always coordinate with your stoma nurse for personalised advice.

Yes. Tested with Coloplast SenSura Mio, Hollister Moderma Flex, ConvaTec Esteem+, B.Braun Almarys, Welland Aurum, NuHope, Pelican, Marlen and Stealth Belt — every major pouch brand.

Yes — that's actually why many SIIL customers came to us. Sea, pool, lake, bathtub. Quick-dry antibacterial fabric. Repels water from your baseplate. Dries in 20 minutes after a swim.

30-day returns, no questions. We refund 100% if SIIL doesn't change your week. We want you to keep it only if it works for you — not because you feel committed.
