I'm considering buying a case of Livdry Protective Underwear (medium). I've never heard of these pullups before, but I found an excellent deal on them. While everyone else seems to sell them for >$1/brief, I've found that I can order them for about $0.60 each.
The pullups themselves are advertised to hold 1.2L of fluid, which beats the comparatively-priced Depends for Men hands-down. These pullups are manufactured as the housebrand of Livdo, which supposedly has the contract for making diapers for Bambino and ABU (see here), so I would expect them pullups to be good quality. However, I cannot find many reviews online for them.
Has anyone ever tried these pullups or heard of them?
