This topic is about finding a modern, non-transparent vinyl or plastic ostomy pouch that matches the qualities of the Marlen MDW-10-201, which has been discontinued. The writer has used this specific pouch for nearly 50 years due to its durability, opacity, and long wear time. However, they are now facing challenges as Marlen has stopped producing the pediatric beige pouch, and the faceplate-making machine is down. They are looking for a new pouch that offers similar benefits.

Here are some helpful insights and advice:

1. The Marlen pouch is valued for its thick, opaque material, silence, and durability, with a wear time of 6-7 days. However, the system is cumbersome due to its design.

2. The writer finds newer pouches from mainstream brands to be flimsy, noisy, and requiring more frequent changes, which they consider a downgrade.

3. To source discontinued Marlen supplies:
- Keep an eye on eBay and medical-estate listings, and buy in bulk when possible.
- A forum member has offered free pediatric Marlen pouches, unused faceplates, and extra bead O-rings to help extend usage.

4. When trying alternative systems and getting samples:
- Request free samples from major manufacturers like Hollister, Coloplast, and Convatec.
- Local ostomy support groups may have samples available for trial.
- Be prepared for some trial-and-error as individual fit and preferences vary.

5. Hollister bags:
- Users report re-using standard Hollister pouches for up to 6 days without tears, even with rough use.

6. Convatec options:
- Convatec two-piece systems with Eakin Seals are more secure and last 4-5 days, proving cost-effective.
- Convatec Natura 2-piece systems regularly provide a 7-day wear time and are gentle on sensitive skin.

7. Coloplast pouches:
- Known for having the toughest pouch material among major brands, though the Click coupling may be unreliable for some.
- Some users mix a Convatec flange with other components for better fastening, though this is not officially supported.

8. Accessory insights:
- Torbot colly seals, Marlen rubberized flanges, and bead O-rings are valued for sealing and silence.
- Pouch covers can help mute rustling and improve discretion if thinner film is unavoidable.

9. Professional help:
- Consult an ostomy nurse for product suggestions tailored to specific size requirements and a high-water-activity lifestyle.

10. Cost perspective:
- While thicker vinyl pouches may be more expensive per unit, their longer wear times can make them cost-effective overall.
