I am not sure if this has already been mentioned (if so, sorry!), but I just wanted to share some success I have recently had.
I have long enjoyed the Depends protection with tabs diapers (formerly 'maximum protection'), with their soft white plastic outer, easy to find purchase them in North America, cheap price, snug fit. The problem has been absorbency. We know one considerable wetting can already result in leaks.
With the launch of the new Goodnites Tru-Fit product, I discovered that those L/XL re-fill pads are actually a very useful and easy to purchase booster pad that fits nicely in the Depends product (or any other adult diaper). For those who have not yet seen them yet, they are like very large incontinence pads, just without the plastic backing. They absorb a lot, but allow the moisture through into the actual diaper. Yes, just like typical boosters.
I am currently sat in my overnight Depends diaper, with two of these Tru Fit pads in it. Without being too graphic, I can confirm that I have used to substantially.. and still, both PJs and bed are completely dry.
When I am not able to order the premium diapers online, this is my new diaper choice. Easy to purchase. Reasonable price. Allows me to custom fit how much additional absorbency I need.
Just thought I would share.
Take care all.
