Support with an inner pocket
Tired of feeling your bag with every move?

When your pouch moves beneath your clothes, you may want a way to keep it closer. An inner pocket lets you carry it close to your body without relying on your trouser waistband to hold it in place.

Choose a wrap to cover your pouch, an adjustable belt to support it or underwear with a pocket: each garment offers a different way to wear it.

SIIL garments include features to hold and cover your pouch with inner pockets, high-waisted cuts and adjustable fastenings, depending on the model. Designed by people with an ostomy, with everyday pouch wear in mind.

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.
