 The news article Mike linked to says "packs to the size of a one liter bottle" - why couldn't they just say "packs down to 1 litre"?  That seems pretty good, certainly in the same ballpark as a lot of the current light inflating mats.

 Also packs down to the size of a 1 litre elephant!

 I don't really want to rush to the defence of the manufacturers, but "packs to the size of a one liter bottle" does give more information - especially about shape - than saying packs down to 1 litre. A cylinder of diameter 1.128 cm and length 10 metres would have a volume of 1 litre but it would be a |* to pack. Their explanation is both specific (1 litre) and descriptive (water bottles tend to be of similar shape). Just don't tell the marketing people that I thought they got it right for once

 Someone will correct me if I'm wrong of course, but I seem to remember recalling a program on NASA astronauts, and they did have an inflatable survival sleeping bag of sorts there, for use on board the Space Shuttle.  It had a kind of a lilo ribbed outer, a kip mat built in onto the base, a hood with plastic face area, plus some kind of electrical circuitry that enabled monitoring of the vitals signs by ground mission control as the astronauts slept I think. It could be hooked up to take oxygen and water supplies for emergency useage. It had to be able to protect the astronaut for sleeping on or against hard objects of equipment in the shuttle; if they ended up ever being all squeeezed into the one final 'panic room' survival cell at the heart of each Space Shuttle - in the event of catastrophe striking, and everyone having to crowd in together to the surviving area of the ship I believe.

And if all else failed they could pull the stopper out of the valve and breathe from it!

 Trev, that was the Rab Apollo. It was weighed 0 grams.

 Oddly enough, I find my Tesco down bag inflates when I've been in it for a while. The outer fabric seems really airtight...
|

But where does the extra 'air' come from...... hmmm, better not do your hood up too tight!

Time for the old Billy Connely joke here then! 'He was about as much use as a fart in a space suit!'

I know of a few folks who use inflatable sit-on Kayaks, and claim that they've happily slept on them in their sleeping bags outdoors!  I don't know if they were being serious or just joking though.
