Total NeoAir convert here, but some folks don't like them so it's good to consider and pretest your complete sleep system before deciding on the components. Part of the decision is how long a pad, as a pillow at the head and and stray clothes/pack at the foot end allow for a shorty pad, which in turn is a big bulk and weight savings.

One thing's certain, it's hard to find anything besides a NeoAir that takes up such a scant amount of pack space. (Maybe a Klymit? I've not seen them on the store shelf, so can't say with any authority.)

Cheers,
