I have a few packs of the new 5 layer protection Goodnites. I am testing them, and have easily used 15 or 20 so far. In a month or so I I ill make a new thread with some specific results.... For now, what I can say is that the size is very similar to the previous version.. possibly *slightly* larger.
The absorbency is EXTREMELY mixed. Sometimes they will hold a lot, whereas others, its like they forgot to add the sap, and they hold next to nothing. I sometimes wonder if they have any Quality Control. I have noticed some of this variability in previous versions, but within these 3 packs its extreme. On the packs that have diapers with codes( on the back right) ending in A or F, its almost like 1/3 to 1/2 of the diapers are under filled/ not filled.
I took 4 or 5 of them ( without looking at the ending letter on the back right) and put them in the bathtub and they did NOT swell up or hold as much water as the previous version... which was disappointing, but I wont draw a definitive conclusion yet, from just a few packs, with diapers of highly variable performance at the beginning of a new design.
They do seem a bit better at taking floods. I think the new padding can absorb faster, and wick much better. It seems like it does a really good job of moving urine through the full length of the pad. When it is first wet with a decent amount of urine... say a 10-15 second flood, the diaper gets a bit stiff ( which I like) Another 15 seconds or so and it gets soft and squishy.
One issue I have is that even for the diapers that do have a lot of SAP, when they start getting full , the crotch starts to sweat/get damp, and also, if you walk and put some pressure on the region, a teaspoon or two of urine will leak out.
Here's an example: This morning, I woke up and had to pee, so I put on a new goodnites. I emptied ~ 90% of my bladder in 2 floods ( 25-30 seconds the first time, and maybe another 20 seconds the second time) This used almost all of the capacity of the diaper and initially, literally just a couple of small drops of pee leaked but after 2-3 minutes, the crotch got damp, and when I walked to turn on the lights, maybe 1 teaspoon of urine leaked to my pajama bottoms.
I also noticed that with the new padding, I tend to get some of the absorbent crystals on my penis. I do get quasihard in the diaper at times, and that can place additional pressure on the padding, but I didn't notice this as much with the previous version. I do wish there was a little more room in the crotch as my junk tends to hang down a bit, and when full, it can put some uncomfortable pressure on my balls.
Edit: **** One thing I noticed is that the new packaging says "More absorbent than training pants" whereas the old packaging says " 0% more absorbent than training pants" That alone make me wonder if they have decreased the absorbency.... If they are now only 25 or 30% more absorbent, they wouldn't want to advertise a downgrade ****
That's all I have for now, but in the relatively near future, I will make a new post with a more detailed and quantitative comparison and write up. Has anyone else tried the new goodnites? Would anyone else like to help with the comparison and measurement?
