Thanks guys! I'm fairly confident they aren't hairless, but I've never seen double rex babies, so I'm not sure :/ They all have wavy/curly hair, some more than others. I'm leaning toward single rex, but time will only tell. I'm kind of pumped, I've been wanting to add some rex into my colony.
Anyway, here's some pics of the proud parents:

Dad and big mama's sister wife:

He does have a light coat of hair on his lower half.
