For those seekers, out there, for highjack PUL plastic pants, I just found this thread in incontinentsupport.org:www.incontinentsupport.org - View topic - Where do I find highback PUL pants?
Which includes a reference to:
Adult Cloth Diapers and Plastic Pants by Angel Fluff Diaper Company Supplier of Adult Cloth Diapers and Plastic Pants
Anglefluff offers PUL pants with a highjack option. They are custom and so cost about half again as much as regular PUL pants do and have a relatively long lead time (the man says up to 16wks Cloyd). They look like they may be better constructed than the usual Gary pants---they have 1 in wide elastic, for one thing.
Once I get them, I'll post a follow-up with my review.
