Welcome, Bill,

What can I say--I love the NeoAir and won't consider anything else at this point. I've used a BA Air Core in the older style and it's not nearly as comfortable or warm. Mind, I'm using a higher R-value model than the Trekker, because I need it in the mountains.

Biggest NeoAir learning point is to not over-inflate, as they're more comfortable with less than a typical mattress. The room they take in a pack is tiny compared to a foam pad.

Can't comment on the others, hopefully others can.

Cheers,
