I like reading about the XP5000, recently got them too. I do like them and they are competitive price wise and one of the cheapest hook and loop with full plastic backing. But in my personal situation I get more out the betterdrys/crinklz before leaking.
At best I can get 900-950 ML when the XP5000 starts leaking, whereas the betterdry I can usually get a solid 1200ML before feeling the need to change and really start leaking only further at 1500-1750ML.
When used the XP5000 just swell even more and are (in my opinion) then more visible under cloths than a fully used betterdry.
I have tried almost all diapers available recently to my list, just the betterdry fits best.
My top fitting diapers are:
tena active fit maxi / ultima for shorter durations or moments to wear less obvious thickness
betterdry the usual suspect for out of house usage
megamax for even longer out of house usage or motorcycle trips, as its just not obvious under motorcycle clothing
I will keep 2 hook an look style diapers in my stash, the tykable cammies blue and the XP5000 for being just so comfortable and other reasons to be able to switch around wearing a little bit.
