Delta Dry Waterproof Cast Padding & Swim Cast Kits
Delta Dry is a two-piece waterproof cast system that uses synthetic stockinette and padding under fiberglass cast tape. The liner feels similar to nylon and allows water to flow through and drain freely, helping patients shower or swim with a cast. Delta Dry is popular in clinics that prefer a familiar wrap-and-pad technique but want the benefits of a true waterproof fiberglass cast instead of a standard cotton-padded cast.

Frequently Asked Questions — Delta Dry Waterproof Cast
Can a patient shower or swim with a Delta Dry cast?
Yes — when applied correctly by a clinician, Delta Dry 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.
How is Delta Dry different from OrthoH2O and AquaCast?
Delta Dry is a two-piece system using separate stockinette and padding layers — 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. AquaCast uses soft pillow-type padding rolls without a separate stockinette. All three create a true waterproof fiberglass cast.
Is Delta Dry compatible with standard fiberglass tape?
Yes. Delta Dry works with standard fiberglass casting tape. No proprietary tape is required, making it easy to integrate into existing clinic inventory.
Who can apply a Delta Dry waterproof cast?
Delta Dry 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.
Is Delta Dry the same as a waterproof cast cover?
No. A cast cover is a removable sleeve placed over an existing cast and is not truly waterproof — it can leak if submerged. Delta Dry is applied under the fiberglass during the casting process, making the cast itself waterproof from the inside out.
Is a Delta Dry waterproof cast FSA or HSA eligible?
Waterproof cast materials applied by a clinician as part of fracture treatment are generally covered under FSA and HSA accounts when prescribed by a physician. OrthoTape is an authorized distributor of Delta Dry products. Contact us for HCPCS documentation if needed for reimbursement.
