What Does 90ml, 200ml, 350ml or 450ml Absorbency Mean?

Absorbency numbers can look very precise, but they are best used as a comparison guide rather than a promise that the garment will manage exactly that amount in every situation.
What Does 90ml, 200ml, 350ml or 450ml Absorbency Mean?

Quick Answer

An absorbency figure such as 90ml, 200ml, 350ml or 450ml describes the amount of liquid the product is designed to absorb under its test conditions. It is useful for comparing products within the same range, but real-life performance also depends on where leakage occurs, how quickly it happens, garment fit and how long the underwear is worn.

What does the ml number represent?

It is an absorbency rating used to indicate how much liquid the garment's absorbent area is designed to hold under test conditions.

Does 200ml mean it will always hold exactly 200ml in use?

Not necessarily. Real-life leakage may be faster, more localised or occur while moving, which can affect performance.

How should the numbers be used?

They are most useful for comparing lower and higher absorbency options within the same product range.

When might a lower absorbency be enough?

Lower absorbency may suit occasional drips or smaller leaks where a slimmer garment is preferred.

When might a higher absorbency be more appropriate?

Higher absorbency may be helpful when leakage is more substantial or less predictable, provided the garment still fits correctly and remains comfortable.

Should you simply choose the highest absorbency?

Not always. A higher-capacity garment may be bulkier than needed. The aim is to match protection to the pattern of leakage rather than automatically choosing the maximum.

What else affects performance?

  • waist and leg fit;
  • position of the absorbent panel;
  • movement and activity;
  • how quickly leakage occurs;
  • how long the garment is worn before changing.

Important: If the garment is repeatedly saturated or leaking around the edges, increasing absorbency may help, but fit and the overall continence plan should also be reviewed.
