Convatec’s Natura closed-end pouches with filter, ranging from SKU 416400 to 416419, represent a premium choice for ostomy care—particularly among colostomy patients. These pouches are designed for one-time use, offering a combination of odor control, user comfort, and discreet wearability. The product line is part of Convatec’s broader SUR-FIT Natura two-piece ostomy system, known for its snap-on design and audible “click” closure, ensuring a secure fit.
This guide covers all 20 SKUs in the 416400–416419 range, explaining how they differ, their features, and how to choose the right pouch for your needs.
2. Product Overview
What Is a Closed-End Pouch?
A closed-end ostomy pouch is designed for single use. It’s ideal for people with regular, predictable output—typically colostomy users. Once the pouch is filled, it’s removed and discarded. There’s no need for draining, clips, or additional sealing mechanisms.
Key Features of Convatec Natura Closed-End Pouches
- Integrated Charcoal Filter: Helps release gas while neutralizing odor.
- Cloth-like Comfort Panels: Quiet, soft material on one or both sides to reduce pouch rustling and skin irritation.
- Secure Snap-On Mechanism: The two-piece SUR-FIT Natura system ensures a solid lock between the pouch and skin barrier.
- Opaque or Transparent Options: For user preference—opaque for discretion, transparent for monitoring.
- Latex-Free Materials: Safe for individuals with latex sensitivity.

4. Filter Functionality and Importance
The charcoal filter is a key distinguishing feature. It allows gas to vent without letting odor escape. This reduces ballooning (gas buildup) and eliminates the need for manual venting, especially valuable in social settings or while sleeping.
Benefits of the Filter:
- Odor Neutralization: The carbon layer in the filter traps unpleasant smells.
- Gas Management: Keeps the pouch from inflating due to trapped gas.
- Discreet Design: Helps users go about daily life with less anxiety.
5. Panel Options and Comfort
The Natura closed-end pouch line features soft, cloth-like panels that add to wearer comfort by reducing friction against the skin and eliminating noisy crinkling. SKUs are available in:
- Two-sided comfort panel: Soft fabric on both sides for maximum comfort.
- One-sided panel: One soft side and one transparent side—for users who want to monitor their output.
6. Skin Barrier Compatibility
These pouches are part of the SUR-FIT Natura two-piece system, meaning they snap onto a compatible flange/baseplate. This system uses an audible “click” to confirm the pouch is securely attached. The skin barrier remains on the body, allowing multiple pouch changes per day without disturbing the adhesive.
Flange sizes covered:
- 32 mm
- 38 mm
- 45 mm
- 57 mm
- 70 mm
Choosing the correct size is crucial to ensure a leak-proof seal.
7. Ideal Users for Closed-End Pouches
These pouches are best suited for:
- Colostomy patients with firm, predictable output
- Active individuals who need a quick and easy disposal system
- Professionals or students who prefer no-drain options in public
- Travelers who require convenience and discretion on the go
They are not recommended for users with high-volume or liquid output, as these require drainable pouches.
8. Application and Removal Guide
How to Apply:
- Clean the stoma area with warm water and mild soap.
- Dry thoroughly to promote good adhesion.
- Snap the pouch onto the flange until you hear the click.
- Smooth the fabric for a discreet appearance under clothing.
How to Remove:
- Gently separate the pouch from the barrier flange.
- Discard the pouch in the appropriate waste receptacle.
- Replace with a fresh pouch as needed.
For sensitive skin, use adhesive removers to avoid irritation during pouch changes.
