I spent a night in one. Not a comfy night. Not sure how those folks got the results they did. Granted, I have the older version, but I'm not convinced that the new one could be that much better. Its also very expensive for what amounts to alumized tyvec. Its not useless, mine is kept on hand as part of my shock management stuff, and as a last-ditch bag, as mine doesn't seem to have the durability that one would expect a multi-use item to have. I'm sure it would add to the thermal value of your kit, but in any kind of humidity it will still be getting wet inside.
For the same price (though not weight) a merino liner is probably going to be more durable, or a tyvec outer cover would do almost as much.
For what its worth, I'm skeptical of the radiated heat claims, and the moisture management. The AMK stuff seems to be heading to more and more marketing. But maybe I just had a bad experience with them, or maybe its just always too humid in SEQ for that sort of thing to work well.
