It seems no two manufacturers use the same language to describe their products. What's "moderate protection" to some is "heavy protection" to others.

Total Capacity Rating Chart

To help you sort it out, we’ve developed a standardized Total Capacity Rating system that we use across all brands and incontinence products we sell. At a glance, the rating shows a product’s ability to absorb and hold bladder and bowel leakage.

Let's talk specifics.

Did you know that adults pass an average of 1 cup (8 ounces or 237 ml) of urine at a time?

Kids are different - there's a calculation based on their age. Look for the "Urine Output Calculation" section to learn more.

Measuring cup - 1 cup - 8 oz - 237 mlFor adults, 1 cup is what's considered a 'full' pee (or, 'void' if you prefer).

When shopping for incontinence products, there are three ways of looking at a person's absorbency needs:

  1. How quickly does the product absorb? 
  2. How much does it hold: drips, leaks, a full void, or multiple voids?
  3. How dry does it stay?

This is where it becomes critical for you to decide what you're looking for, based on your needs. Are you looking for protection against:

  • Occasional drips over several hours? Or
  • Small, unexpected leaks (like after a sneeze)? Or
  • Slightly larger leaks - like after you lift something, or jump or skip - that leave you feeling wet?
  • Or, unpredictable, full (and possibly repeat) voids where you need to change your clothes?

Understanding the protection you need - which can also change over time - is the key to picking the right product. Perhaps you need LIGHT protection during the day but MAXIMUM protection overnight. We've explained what each rating level means below:

Watch for the rating on every product listing on our site to make sure the products you choose are right for you.
