If you're going to be out any nights below 40* F, you need an insulated air pad--either the Pacific Outdoor Equipment Ether 6 or the Big Agnes insulated air pad.

I found the NeoAir far less comfortable and also got cold below 40*. Below freezing the NeoAir requires a thick CCF pad for extra insulation, which does away with any weight savings over the POE or BA insulated air pads.

Note that any air pad should be blown up only part way. A fully inflated pad is about the same as sleeping on a brick. My best results are with my POE insulated air pad blown up about halfway--keeps my hips off the ground but keeps my spine level when I'm on my side (I do have "ample" hips!).

Whatever you get, spend several nights on the floor with it to make sure it works for you before taking it out in the field.

I have my eye on one of those Kooka Bay down mats for the future.
