I don't know how no one has discovered these covers....

Big W, Cuty brand. They are a cream colour, made of polyester fleece (so they wick moisture like wool) with a pvc leg gusset and pvc lined polyester "slingy" bit across the crotch.

you cut the pvc off the back of the crotch bit, and taa daa - you have a $4 fleece cover that's the same shape as a motherease rikki! the leg gusset, unfortunately pvc - is such a small amount that it certainly doesn't give rashes or hold in the heat.

in fact, I have had dd wake early 3 nights in a row while wearing this cover because the moisture evaporating from her cover gave her a freezing bum! will be great for summer - although at the moment we have gone back to pul. we haven't had any leaks or wicking that wet the clothes etc - just like a wool cover really. I haven't even noticed compression wicking.

just thought I"d let people know tha tthere are great very cheap fleece covers out there that are a great backup for a pul or two.
