Adult diaper covers hold cloth diapers, flat adult diapers or incontinence insert pads in place. Compatible absorbent products vary by cover, and comfort depends on size and application. This illustrated guide explains the role of diaper covers, combinations, sizing and precautions.

Diaper covers

Diaper covers hold cloth diapers, flat adult diapers or incontinence insert pads in place to help prevent leaks. Their main feature is that they can be washed and reused. With the spread of disposable adult diapers, covers are now used less often in Japanese older-person care.

Combinations

Here are three combinations.

Cloth diapers only (not recommended)

Place rectangular cloth diapers inside the cover according to urine volume.

Advantages

• Pleasant against the skin before elimination

• Washable and economical

Disadvantages

• Strong discomfort after elimination

• Layering several makes the diaper bulky

Flat adult diapers only (not recommended)

Flat absorbent sheets have relatively low capacity for their size. Gaps can form, making leakage more likely.

Advantages

• Disposable

Disadvantages

• Poor breathability

Incontinence insert pads

Diaper covers specifically designed for disposable pads are available.

Advantages

• Wide choice of absorbencies

Disadvantages

• Higher cost

Hiroshi Yagi

In practice, cloth diapers and flat sheets have limited absorbency, so incontinence insert pads are often added on top. Take care that the resulting bulk does not restrict movement.

Choosing the right size

Size labeling varies by manufacturer. Check the product labeling before purchasing.

Key point

Some sizes are expressed by hip measurement, but choose a fit that is neither tight nor too loose around the waist and groin.

Diaper covers: Points to note

Strong compression

Loosening a diaper cover around the thigh with a finger to adjust tightness

Depending on the product and size, the cover may feel uncomfortably tight around the thighs. Gently inserting a finger into the gap to release pressure can ease the pulling sensation slightly. Some people develop pressure marks from excessive tightness.
