OrthoH2O is a professional-grade waterproof cast liner system that enables clinicians to create a true waterproof fiberglass cast — commonly called a swim cast. Unlike a removable cast cover, OrthoH2O is integrated directly into the cast during application, allowing patients to shower, bathe, and swim throughout their recovery.
The liner is a thick, fishnet-style cylindrical stockinette that slips over the limb before fiberglass cast tape is applied. Water flows through the open mesh and drains freely from both ends — no trapped moisture, no skin breakdown.
OrthoH2O is a direct clinical alternative to AquaCast and Delta Dry waterproof cast systems. All three allow water drainage through the liner, but differ in design and application technique.

Yes — when applied correctly by a clinician, OrthoH2O creates a cast that allows full water exposure. The mesh liner lets water pass through and drain out, preventing moisture buildup that would otherwise soften a traditional cast. Patients should always get clearance from their physician before swimming.
Yes. OrthoH2O stockinette works with standard fiberglass casting tape. No proprietary tape is required, making it easy to integrate into existing clinic inventory.
A cast cover is a removable sleeve placed over an existing cast — it is not truly waterproof and can leak if submerged. OrthoH2O is applied under the fiberglass during casting, making the cast itself waterproof from the inside out. No removal is needed before showering or swimming.
OrthoH2O 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.
OrthoH2O is a one-piece slip-on mesh stockinette — faster to apply than multi-layer systems. AquaCast uses soft pillow-type padding rolls wrapped around the limb. Delta Dry is a two-piece system with a separate stockinette and padding layer. All three create a true waterproof fiberglass cast and are compatible with standard fiberglass tape.
