BLOCCS 100% Waterproof Arm Cast Cover - Adult Long Arm

In this review of the BLOCCS 100% Waterproof Cast Cover (ALA72) the bottom line is simple: this sleeve is for adults who need reliable, reusable water protection for an arm cast, bandage, or wound dressing. The single biggest reason to buy is its watertight performance during showers and swimming, backed by a soft natural rubber that stays comfortable over extended wear. The review covers fit, material, and real use cases so shoppers can decide if the 30 in long sleeve and seal range meet their needs.

Key Features

• Waterproof protection: Keeps casts, bandages, and wound dressings dry for bathing, showering, and swimming without allowing water ingress when used correctly.
• Adult sizing: Designed to fit a seal circumference of 10 1/2 - 15 1/2 in with a 30 in cover length, making it suitable for most adult arm casts and longer dressings.
• Natural rubber construction: Made from soft, flexible natural rubber for a comfortable, snug seal that bends with the arm and reduces chafing.
• Reusable and durable: Built to withstand repeated use for showers or pool visits, offering a longer-term solution than single-use covers.
• Made in the UK: Manufactured to medical-grade standards and trusted by healthcare professionals for protecting dressings in water.

Who It's For

The BLOCCS ALA72 is best for adults recovering from arm or hand injuries who want to remain active and keep wounds or casts dry while showering or swimming. It suits users who value a durable, reusable sleeve rather than disposable options, and those who can accurately measure both cast circumference and length before ordering.

People who should look elsewhere include those needing pediatric sizes, or anyone who cannot tolerate a snug rubber seal; customers with very bulky or irregular casts should confirm fit carefully against the size chart before purchase.

Pros & Cons

Pros

• Reliable watertight performance that keeps casts and dressings dry in showers and pools.

Cons

• Some users report the sleeve can feel tight and difficult to put on, especially over bulkier casts.

Frequently Asked Questions

Will this cover keep a cast completely dry?
When sized and applied correctly the sleeve provides watertight protection for casts and dressings in showers and pools, though care is needed to ensure a proper seal.

How do I choose the right size?
Measure both the circumference where the seal will sit and the length of the area to be covered; the ALA72 fits a 10 1/2 - 15 1/2 in seal circumference and is 30 in long.

Can this be reused?
Yes, the sleeve is durable and designed for repeated use, but because it contacts medical dressings it is non-returnable once opened.
