Marine Underliner

Marine Underliner is a breathable, water-resistant fabric engineered for use in boat upholstery, RVs, and other moisture-prone interiors.

Its durable construction ensures reliable performance even in harsh marine environments, making it an essential component for long-lasting interior comfort and hygiene.

Popular applications include:

- Boat cushions & seating

- RV & camper mattresses

- Marine & recreational upholstery

- Protective underlays for foam & padding

A practical and durable solution, Marine Underliner combines moisture management with ventilation and protection, delivering comfort, longevity, and a professional finish for marine and mobile interiors.
