The Megamax diapers are pretty good, after wearing my first one. I weighed one and then put it on. The Megamax is actually lighter in weight than some other my other diapers.
The fit for me is good and the diaper is comfortable. I had a good fit, but decided to adjust the tapes to see how well they hold up. As others have said, it takes some effort to untape these tapes. I wet the diaper and I could barely feel the first wetting, other than the warmth. I consumed some fluids and had a couple more wettings without issues. Then I went to bed.
I woke up with an urge to pee, so I let it out and the diaper continued to swell. I let out moderate wettings, nothing that I would consider a flood. The diaper was still very snug. I got up and walked around the house and sat down in a wooden dining room chair. No leakage and the front of the diaper was pretty swollen. Not much moisture in the seat of the diaper.
Even though the fit was still good, I decided to adjust the tapes again, several times. One time, I even untapped all four tapes and reapplied the diaper. A few more smaller wettings, followed by sitting in the chair for a few minutes. Sitting down seemed to put stress on the tapes, as it felt even tighter than when standing, but the tapes held.
When I noticed a small leak, I stopped wetting the diaper, but continued to move around and even re fastened the tapes again.
The tapes are incredible on these diapers. I had the diaper taped on very tight and they never failed.
When I finally took the diaper off and rolled it up, I was a little bit disappointed. Even though the diaper had swollen up huge in the front and groin area, when I rolled up the used diaper, it didn't seem much different than other diapers that I've used.
The wet diaper weighed 3 pounds, 9 1/4 oz. The diaper weighed a little bit over 7 oz. dry before I put it on, so we'll call it a 3lb 2oz. change in weight. Doing the math, it works out to 48 fluid oz. of capacity. That is what Northshorecare rates the Megamax large diaper capacity at. I was thinking, or hoping that they were under estimating the capacity, but it was dead on, at least for this one test.
The Megamax does have some crinkle noise as I walked around the house, in just the diaper. Putting on a pair of jeans and walking around the house, I couldn't hear the sound anymore. The diaper is somewhat concealable when dry, but swells up quite a bit when wet.
The tapes are really what make this diaper stand out, I think.
