AquaCast is a soft, pillow-type waterproof cast padding used under fiberglass cast tape to create a true waterproof cast or swim cast. The padding is wrapped around the limb and finished with fiberglass, allowing water to flow through and drain freely instead of soaking into cotton. AquaCast waterproof cast kits are popular for kids and active patients who need to shower or swim with a cast.

Yes — when applied correctly by a clinician, AquaCast creates a waterproof fiberglass cast that allows showering, bathing, and swimming when approved by the healthcare provider. Patients should always follow their provider's cast care instructions regarding water activity.
AquaCast uses soft, pillow-type padding rolls wrapped around the limb before fiberglass is applied — the same familiar wrap-and-pad technique used with standard cast padding. OrthoH2O is a one-piece slip-on mesh stockinette that can be faster to apply. Delta Dry is a two-piece system with a separate stockinette and padding layer. All three create a true waterproof fiberglass cast.
Yes. AquaCast waterproof padding works with standard fiberglass casting tape. No proprietary tape is required, making it easy to integrate into existing clinic inventory.
AquaCast is a clinical product intended for application by orthopedic technicians, physicians, or trained casting staff. It is not a DIY product. Proper application technique is required to achieve a truly waterproof result.
No. A cast cover is a removable sleeve placed over an existing cast and is not truly waterproof — it can leak if submerged. AquaCast is applied under the fiberglass during the casting process, making the cast itself waterproof from the inside out.
