There's the brand-new Nemo Switchback:  It's supposed to provide a thicker pad but that folds up to the same size as the Z-Lite. For myself I just got a non-name off of eBay, it's extremely similar to the Z-Lite without the silver or yellow coating, less than $15 shipped. EDIT: I only use it with an air pad when cold. |

No clue. Both look nice.

Yeah. It uses a different type of foam and features hexagonal nodes, which are molded with a our [sic] dual-density Axiotomic™ foam to create Hypnoelastic™ zones that conform to your body in a perfect balance of comfort and support.Whatever that means. And they don't provide an R rating, which makes my spidey sense tingle.
Have you used one?

features hexagonal nodes, That both intrigues me and scares me. More seriously reuben, what does R value mean? Obviously the higher the R value, the more insulation it provides. Is there a way to correlate R value to ground temperature insulation? |

Screw that! Although I would imagine BPL folk are all over it.

...zones that conform to your body in a perfect balance of comfort and support.Whatever that means. It means it's not very comfortable and doesn't give much support. |

It means it's not very comfortable and doesn't give much support. On the other hand, if it does conform to [my] body in a perfect balance of comfort and support the rest of y'all are screwed.

It's a measure of the resistance to heat flow, the inverse of the overall thermal conductance. Heat flow is proportional to the temperature difference (between your body and the ground) divided by the R value. HeatLoss ~ (T_me - T_ground) / R |

Yeah, hence the "R" value.

If you have a BPL membership, they have a pretty in-depth review: link. I don't get the impression from the review that it is a significant improvement over the Z-Lite. Though they don't provide an R-Value, they rate the pad for 20-35 degrees. My understanding is that the theory behind that Klymit pad is that it allows your sleeping bag to loft underneath you to provide insulation. Never tried one myself, but it's an interesting strategy. |

Kinda makes sense. Would be a bust for quilt users. I move around too much for it to work for me. I guess if one is a back sleeper and doesn't toss and turn it could work. |
