They are going to custom-create a better fit for my small arm. I'm a 5'2" woman with a wrist cast. I bought the adult half-arm (9.0β€³-12.5β€³ Circumference Above Cast - For Hand & Wrist). My arm was at the bottom limit for his fit, and actually with a snugger measurement is more like 8.5" (thanks to no muscle tone from the inactive arm). NOTE: The child's size is too small. I needed a snugger fit so I can swim. The one I bought will work fine for the shower. It's well-made and I'm glad to see it's 100% Made in the USA. What amazing customer service!! If you have a smaller arm, just call Diane! I suggested they need to manufacture a petit adult size to fit women. Review: WORKED FOR 10YR OLD FOR SWIMMING - This worked amazing to allow my son to still be able to swim while on a preplanned vaca. He was bummed when the cast was put on week before vaca. The one thing I will say is if planning on using multiple times may want to buy more then one. After few days of using the opening does stretch out and will allow water in. ( We used excessively though multiple times a day) worked great for when he showered as well. It is extremely tight and will cause a ring around the arm so I don't recommend wearing for long periods of time but I highly recommend this product especially for children. Makes keeping the cast dry so much easier and doesn't restrict the kids from water stuff in the summer. ## Features - Watertight Seal Guaranteed: Measure your arm circumference above the cast or bandage for a perfect fit.

I wasn’t able to get it over the soling and the bandages. It probably works better with a cast. ## Frequently Bought Together - AquaShield Reusable & Waterproof Cast Cover for Adult Half Arm (A21) - Bandage Protector for Plaster, Bath, Shower, Pool, Swimming (9.0β€³-12.5β€³ Circumference Above Cast - For Hand & Wrist) -Made in USA - Cast Scratcher and Cleaner/Sanitizer Gifts for itching and Cleansing cast Covered arms and Legs - 100% Waterproof Cast Cover Arm - [Tight Seal] - Easy to Use - 3pk - Reusable Half Arm Adult Π‘ast Π‘over for Shower Arm, Hand & Elbow - Waterproof Arm Cover for Shower --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/9667795-arm-cast-protector-waterproof-reusable-half-arm-a21-covers-hand](https://www.desertcart.pt/products/9667795-arm-cast-protector-waterproof-reusable-half-arm-a21-covers-hand) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
