A sleeping bag that coils itself up into a tight roll when you get out of it. Much like the old metal rulers that are concave along the length. Extremely firm when extended, but coil up tight when stored. The only trick is to prevent it from coiling while sleeping!

Whats with all the curly ideas of late? +

So it's concave along it's length...until you get into it and flatten it. Then it rolls up with you in it.

you would have to hook both ends to a wall like a hammock.

It could work like those snap bracelets.

hows that?

If it rolled into a case like a measuring tape, then it could have a ‘hold open’ button just like a measuring tape. (+)

Good idea - if the case is small enough and square for stackability.

Would the bag have markings along the side, so one could ascertain the number of mm one has grown during the night?

grow bags are baked.

Well, do they come about 12 inches long and two in diameter?

alternate idea: the case for the sleeping bag has a little air pump in it, and so the sleeping bag is capable of vacuum packing itself. by expelling all the air form teh container, you can get it not only smaller, but lighter as well.

There are self-inflating sleeping bag mattresses...perhaps this could work in somewhat the same way.

Perhaps a crank on the end of the case letting you, well, crank that baby into a super-tight roll. Hang a motor on it?

How did rods get from mentioning snoring to being taken out and broken down? Wasn't he already broken down? I'm confused, fogfreak.

tim, in order to behave like the metal ruler you refer to, wouldn't the sleeping bag also have to be made of metal? That sounds a bit uncomfortable. There are plastics out there with a pretty good memory for shape. Perhaps making the underside of the sleeping bag out of a sheet of heavy-duty plastic that you place curly-side down to sleep on would work. When you get out of the bag the underside tends to return to its original shape, curling the bag right up (or should that be right down?) again.

Johnathan Michealevitz passed away suddenly today from a freak camping accident. He was sleeping in his "Selfstora-sleeper", when the spring tensioner device malfunctioned, and rolled him up like a curly fry. He possibly would have survived, if not for the vacuum sealer motor that switched on during the recoil process of the sleeper. Witnesses say when they woke up they found Mr. Michealevitz rolled up into a nice neat twelve inch circumferenced ball.

That's the basic idea of a compression pack for a sleeping bag, only it doesn't depend on a perfect seal.

The problem is the compression bags are too small. If you had a bigger pack that could squeeze as tight, it'd work.

BTW, check for chocolate bars in the back before storing your sleeping bag.
