In short, yes they can! Except, there are some things to consider when using them for this use. Firstly, at House of Callaway, we tend to use cottons (or polycottons) to top our pads. These often absorb fluid more slowly but improve over time after repeat washing. If you are using our pads for slight leaks, keep in mind that the dry-feeling you might get from the pad will naturally improve slightly over time.
Another thing to keep in mind is your personal needs. We don't like to mislead customers by saying all of our products suit absolutely everyone perfectly because we know that everyone is different. If you have a lower level of bladder weakness, for example, when coughing, sneezing or lifting heavy things, our pads would probably suit you well. However, if you're someone who experiences full-release incontinence or similar, we'd recommend researching other options or speaking with your health practitioner for any recommendations they may have. We always tell anyone who isn't sure though to just try the one pad first to check it fits your requirements then come back for more - we never want you to spend your money on something that didn't serve the purpose you need!
On a final note, if you choose to message us looking for advice or product recommendations on this topic, we can often modify our current designs to fit personal needs. For example, a common modification we do is to replace the terry towelling layer in our 'light' pad for a zorb layer to ensure maximum fluid absorption. This idea has proven popular with many customers with bladder weakness.
If you're curious about cloth pads for bladder weakness, please feel free to drop us a message, we'd love to help!
