Yeah, I was more skeptical of the IR reflection model than the appeal of going back to an air mattress after foam pads and self-inflators, but darned if it doesn't work and it's perhaps the most significant volume-saving gear swap I can think of. Turns out the horizontal tubes (vs. lengthwise) do a great job eliminating typical air mattress bounce. My main "discovery" achieving best comfort was avoiding over-inflation.

Cheers,
