100% Polyester knit laminated with 1 mil waterproof, slightly-breathable backing. Approx. 58/60" wide
PUL stands for polyurethane laminate and I pronounce it "pull" but some people spell it out. It can withstand washing in hot and drying on hot. It is very durable. I have known people to use the same PUL diapers for over 3 years so it has been thoroughly tested and will stand up to the rigors of cloth diapering.
