This topic is all about finding ways to keep an ostomy barrier secure and ideally dry while enjoying activities like swimming, bathing, or relaxing in a hot tub. Here are some helpful tips and insights to consider:

1. Consider using products specifically designed for water:
- The Cymed one-piece pouch with Microskin and an integrated hydrocolloid washer is highly recommended. Users have reported that it stays secure even after spending a whole day in the ocean.
- Adding an extra barrier ring to the Cymed system can extend its wear time from 2-3 days to 5-7 days.
- Learning the proper Microskin application technique is important, but it's easy to pick up.

2. Experiment with different brands to find an adhesive that works well for you in water. Many companies offer free samples. Swimmers have recommended:
- Coloplast SenSura one-piece.
- Coloplast Mio, which one swimmer uses for daily wear.

3. Reinforce the wafer with waterproof overlay products:
- SureSeal Rings are thin, transparent films that cover the entire wafer edge and stick to the skin. They are reported to stay sealed in showers, pools, hot tubs, and water parks.
- Coloplast Brava Elastic Barrier Strips are half-moon "banana" strips that encircle the flange. Many users find them very reliable in the pool and easy to remove. If they swell and lift immediately, it might be a faulty batch, and contacting Coloplast is advised.
- Micropore tape can provide extra edge security for some people.

4. Combine systems for added security:
- A combination of a Hollister two-piece system, a barrier ring, SureSeal, and an ostomy wrap worn under swim shorts has been reported to maintain a normal 5-7 day wear time without pool leaks.

5. Use supportive garments:
- Swim wraps and belts from OstomySecrets.com can help hold pouching systems flat and discreet.
- A snug, close-fitting swimsuit or a wrap under trunks can keep everything in place while swimming or snorkeling.

6. General tips:
- The pouch itself doesn't need to stay dry; focus on keeping the wafer/adhesive secure.
- The right appliance and overlay combination can handle sweat, hot tubs, and salt water.
- If a product doesn't work well, ask the manufacturer for newer samples, as adhesive formulas and stock age can affect performance.
