This topic is about finding a reliable, leak-free one-piece ostomy appliance for someone who leads a very active lifestyle. The person has been using a specific product for years, but recent changes in the product's design have led to issues with leaks. They are looking for recommendations on products that can withstand activities like running, exercising, working, and walking the dog, while providing at least two days of wear time.

Here are some suggestions and insights that might help:

1. Consider trying other Hollister one-piece models:
- The Hollister 8371 drainable pouch, when used with the Hollister/Adapt barrier ring 7805, has been reported to provide up to four days of wear.
- The Hollister 8962 pouch, combined with Hollister convex barrier rings, is another option. Some users change it every other day due to leakage but still find this combination preferable.
- Contact Hollister customer service to inquire about newer designs and request samples, as the 3238 model might be outdated.

2. If you switch from pre-attached seals, consider adding a barrier or seal accessory:
- Use the Hollister/Adapt barrier ring 7805.
- Eakin rings or ostomy paste can be applied under the flange to strengthen the seal.

3. To minimize pouch movement during activities like running, use a support belt:
- The vertical StealthBelt provides vertical bag support.
- The NU-Hope belt, Movi Brace belt, and similar ostomy belts offer circumferential pressure around the flange.

4. Be mindful of external factors that might affect adhesion:
- Avoid using soaps, moisturizers, or skin products that could interfere with the adhesive.
- Any changes in your skin-prep routine might reduce wear time.

5. General technique tips:
- Ensure your skin is completely dry before applying the appliance.
- Consider using a belt or ring even if your stoma is flat.
- Try out different products until you find one that consistently provides a two-day wear time.
