Cotton Cast Padding vs. Synthetic Cast Padding — Why Clinics Are Making the Switch
For decades, cotton cast padding was the standard in orthopedic casting. It was soft, widely available, and familiar. But cotton has a fundamental problem: it absorbs moisture and holds onto it. Sweat from the patient's skin soaks into the cotton fibers and stays there — creating a warm, damp environment under the cast that leads to odor, skin irritation, and padding breakdown over the wear period. In long leg and hip spica casts — where patients wear the cast for weeks — this is especially problematic.
Synthetic cast padding was developed specifically to solve this problem. Made from polyester fibers engineered to wick moisture away from the skin rather than absorb it, synthetic padding keeps the cast environment significantly cooler and drier than cotton — a meaningful quality-of-life improvement for patients in large casts worn over extended periods.

Cast Padding for Sports & Athletic Use
Beyond orthopedic casting, cast padding for sports has become a popular application. Athletic trainers and sports medicine staff use 6-inch cast padding rolls as extra cushioning under thigh braces, hip orthoses, and large-joint protective equipment. The 6-inch width provides fast, broad coverage for the thigh, hip, and torso. Synthetic cast padding is preferred for sports use because it wicks moisture during activity, dries faster between uses, and stays lighter than cotton alternatives.
⚠️ Synthetic Padding ≠ Waterproof Cast Liner
Synthetic cast padding handles moisture better than cotton but is not a waterproof cast liner. For patients requiring a fully waterproof cast, a dedicated waterproof liner (such as AquaCast) must be used.

Frequently Asked Questions
What is cast padding used for?
Cast padding (also called undercast padding) is applied directly over the skin and stockinette before fiberglass or plaster casting tape is applied. It protects bony prominences, cushions the skin, and provides a comfortable interface between the patient and the hard cast shell. It is also used in sports as extra cushioning under braces and protective equipment.
Is synthetic cast padding better than cotton cast padding?
For most modern orthopedic casting, yes. Synthetic polyester padding wicks moisture away from the skin rather than absorbing it like cotton does. This results in a cooler, drier environment under the cast, faster dry times after sweating, reduced odor, and lower risk of skin irritation. In long leg and hip spica casts worn for weeks, this is especially meaningful for patient comfort. Cotton cast padding was the standard for decades but has largely been replaced by synthetic padding in modern clinical practice.
Is OrthoTape cast padding waterproof?
No. OrthoTape synthetic cast padding handles moisture better than cotton but is not a waterproof cast liner. For a waterproof cast, a dedicated waterproof liner (such as AquaCast) must be used as part of a complete waterproof casting system.
Can cast padding be used for sports?
Yes. 6-inch cast padding rolls are used in sports medicine as extra cushioning under thigh braces, hip orthoses, and large-joint protective equipment. Synthetic cast padding is preferred for sports use because it wicks moisture during activity, dries faster, and stays lighter than cotton alternatives.
How much cast padding do I need for a long leg or hip spica cast?
Long leg casts typically require three to five 4-yard rolls of 6-inch padding depending on patient size. Hip spica casts may require more. Apply with 50% overlap and add extra layers over bony prominences such as the knee, malleoli, and heel.
