Hi there, sorry to hijack
What is PUL? I'm occassionaly using terry flats with the PVC pants but I don't like them!
if you google

"PUL"

you get great definitions popping up. if i was allowed to post you a link i would!

PVC covers are all sweaty, crack, break, leak etc
PUL is streets ahead
if you have never bought one before, you can get PUL covers with snaps like the Wonderwraps at darlingsdowunder (a one size fits all cover)

or sized aplix closing PUL covers from baby beehinds.
APLIX is industrial velcro that stands up to the repeated washing that nappies go thru.

other waterproof cover options these days are:

- double layer polar fleece covers
- maldenmills windpro covers (esp for night)
- woollies in the shape of a cover, often called SOAKERS. they work by being LANOLISED, you only wash them once a month.
