Sounds wonderful! I've heard of the fleece clothing made from recycled plastic, so this is no surprise for me.
One caveat I had with laundering fleece anything, was in my Kenmore stackable dryer, I could not trust it to not singe the fleece, making a hard plastic sandpaper area out of the fuzzy soft fabric. It happened a couple of times on lowest heat setting, so I had to hang all fleece to dry after that lesson. I sold the set when we moved, to avoid moving them, and bought a standard dryer, larger capacity and have not had the problem, even though it is an older dryer, the low heat setting doesn't heat the back of the dryer in the same way to allow a hot spot to develop. A bit off topic, but something to watch out for with any exposed fleece in dryers.
