My pad from the late lamented KookaBay isn't crinkly, but it does occasionally let out a loud squeak if I turn over too abruptly.

While I had lots of objections to the NeoAir, the alleged noise wasn't one of them. With a sleeping bag hood over your ears, a lot of sound is blocked! (As Glenn has found out in Ohio summers when the thought of a puffy hood about one's ears is enough to produce instant heat stroke.)
