BLOCCS waterproof cast cover for kids arm (Small) — 17in natural rubber sleeve, leak‑proof seal for shower & swimming

BLOCCS CA79-S is a small, 100% waterproof arm sleeve designed to keep a child’s arm cast, dressing, or bandage completely dry during showers, swimming, and water play.

When a child has an arm injury or wound dressing, staying active and clean can feel tricky. The BLOCCS small arm cover (CA79-S) offers a flexible, natural-rubber barrier that seals around the arm to prevent water intrusion while allowing kids aged approximately 3–6 years to bathe or enjoy water activities with confidence. Its dimensions and seal circumference are tuned for smaller arms, so measuring before purchase ensures the best protection.

How do I know the CA79-S will fit my child?

Fit is key to a reliable waterproof seal. The CA79-S is sized for small children and lists both seal circumference and cover length to guide your choice. Measure the arm where the sleeve will seal and compare that to the product dimensions to avoid leaks.

• Seal circumference fits approximately 6¾–7½ inches.
• Overall cover length is 17 inches to protect from wrist to upper arm or elbow.
• Recommended age range about 3–6 years as a general guideline.
• Follow the sizing chart and measure the arm at the intended sealing point.

Can this sleeve be used for swimming and showering?

Yes — the sleeve is engineered to keep casts, dressings, and open wounds dry in both still and moving water. Its waterproof construction is suitable for showers, pools, beaches, and waterparks, letting children participate in water-based activities while minimizing moisture exposure to the protected area.

• Designed for water exposure like showers and pools.
• Durable seal reduces risk of water reaching the cast or dressing.
• Flexible material adapts to arm movement during play or bathing.
• Rinse and dry after use to maintain hygiene and longevity.

What material is the sleeve made from and how comfortable is it?

The cover is crafted from natural rubber that balances durability with flexibility. The soft, elastic material forms a gentle, conforming seal without rigid edges, making it more comfortable for children to wear while remaining effective at blocking water.

• Made of sustainable, natural rubber for softness and stretch.
• Helps maintain a snug seal without pinching or extreme pressure.
• Clean with mild soap and air-dry; avoid harsh chemicals to preserve material.
• Store flat and away from direct sunlight to prevent deterioration.

How should I care for and use the BLOCCS arm cover safely?

Proper use extends the life of the sleeve and improves protection. Always check the seal and material before each use, and follow simple care steps to keep the cover in good condition and working as intended.

• Check for tears or punctures before every use; discard if damaged.
• Slide the sleeve on gently, ensuring the sealing edge rests evenly around the arm.
• After use, rinse with fresh water, mild soap if needed, and air-dry completely before storage.
• Store in a cool, dry place away from direct sunlight and sharp objects.

Who is this for? Parents and caregivers of small children (roughly ages 3–6) recovering from arm injuries, wearing casts, or using dressings who want a reliable, comfortable waterproof solution for showers and water play. BLOCCS CA79-S is useful for active families who need a durable, reusable cover sized specifically for smaller arms. Always measure the arm at the intended sealing point and consult medical guidance for wound or cast care as needed.
