When most people think of a cast, they imagine a heavy plaster shell that becomes uncomfortable, traps moisture, and makes everyday activities difficult. Cast21 takes a different approach. Its immobilization net is designed to provide support while allowing patients to stay more comfortable during recovery.
The result is a lightweight, breathable, and completely waterproof cast that looks very different from traditional options.
Built for an Active Lifestyle
One of the biggest challenges with conventional casts is keeping them dry. A shower, a rainy day, or a trip to the pool can quickly become a problem.

3. Open lattice structure allows airflow around the skin.
Cast21 is designed to eliminate many of these concerns. Because the open net structure is waterproof, patients can shower, stay active, and even swim while their injury heals. The breathable design also helps reduce the sweaty, uncomfortable feeling often associated with traditional casts.
Fast and Simple Application
The application process is designed to be quick and efficient. First, a flexible sleeve is placed around the injured area. The sleeve is then filled with a fast-curing resin. Within minutes, the material hardens into a supportive structure that helps immobilize the injury.
The entire application takes about three minutes, allowing healthcare professionals to fit the cast quickly.
Comfortable Support During Recovery
The open design allows air to circulate around the skin, helping improve comfort during the healing process. Instead of being completely enclosed inside a solid cast, patients benefit from a structure that provides support while remaining breathable.
This approach helps make daily life easier while still delivering the immobilization needed for recovery.
A New Direction for Orthopedic Casting
Cast21 shows how orthopedic casting technology is evolving. By combining a lightweight structure, waterproof materials, and a fast application process, it offers an alternative to traditional plaster and fiberglass casts.
For patients looking for a more comfortable recovery experience, Cast21 provides a modern solution that supports healing while allowing greater freedom in everyday life.
