I missed the insulated part in his post. My bad. BA makes an Air Core too. I was confused.
The main downfall of the IAC is its weight. Even the mummy is 21 ounces but the full rectangle pad is 24 ounces.
While heavier it has kept me warm even below zero a couple of times. I can't say the UL7 has done that for me. The comfort rating started dropping out around 25degr. for me.
Great early season pad though.
