FAQs: Common Ostomy Underwear Questions

Find the right garment for you

Choose a belt for adjustable pouch support, a wrap for coverage under your clothes, underwear for everyday comfort or swimwear for time in the water. Each product page explains its fit and how it holds your pouch.

Our pocketed garments hold your pouch closer to your body and help smooth its outline. How discreet it looks depends on your pouch, how full it is, the garment’s fit and the clothes you wear over it.

The SIIL Belt has an access opening so you can reach and empty your pouch while keeping the belt on. Access differs between garments; check the details on the product page you choose.

Use the size guide on the product page you are shopping. Follow the measuring instructions for that product: belts and other garments use different size charts. Ask our team if you need help.

You can request an exchange or return within 30 days of delivery, subject to the return policy conditions. Try the garment on carefully when it arrives and contact our team for help.
