I've had some of the cotton and some of the bamboo fabrics for about 5 years now and I was always quite happy with them. I'm just as happy with the newer styles as well. They're exactly what they claim to be. I've only ever had a minor issue periodically, where I have to manually tuck my boy into the front pocket because he didn't want to slip in nicely himself. Totally minor issue. Overall, really spectacular.
