I'm trying to decide between an abena M2 or an M3. I would be wearing it under my clothes in public. Does anyone have any experience with either or both of them? xpmedical claims that they're both 0.3 inches dry. Honestly, I would mostly be wearing them in public for the enjoyment of the bulk when dry, and not really for their intended purposes, but I might. Would both be equally discreet under normal jeans when dry? How much bulkier do the M3's get compared to m2's when wet? Does one flare out more than the other? I really don't want any obvious diaper butt, but if I'm not going to use them while out, I'd rather get the M3's in case I decide to use them in my apartment when I get home. Also, are they both white with that blue design like the M4's?
