Touring - Double sleeping bags

Does anyone here know of a decent manufacturer of double sleeping bags? The only ones I can find are heavy, sqaure caravan types but what I want is somthing a bit more suited to touring (lightweight, compact yet warm).

It seems to me that a double bag would be lighter, more efficent and, well, more social than two single bags.

You could just zip two bags together.

Besides, one large bag is MUCH more social. ;)

We have sleeping bags with right-handed and left-handed zips that allow us to zip them together.

I use a North Face 'Chrysalis' which has the capability of being completely unzipped flat, and then a ripstop nylon 'bottom sheet' is zipped in for the bottom portion.

I'm also interested in an answer to BananaMan's question. Zipping two bags together is not the answer. You end up carrying more sleeping bag than necessary, and it's not as warm because there's way too big an opening at the top.

At the bottom of this page:

you can read about a Birdland (Netherlands) sleeping bag that a couple cyclists had custom made. It's smaller, lighter, and warmer than zipping two bags together. Anyone know of other manufacturers?

I've heard about solutions like bunabayashi suggests and might look into it.

I'm a fan of zipping two bags together. Works great for a couple reasons: 1) I am long, so I need a long bag, but my GF is not as long & only needs a standard bag. My Marmot bag has a standard length zipper that works with most bags from quality mfrs. B) I am a hot sleeper, so need less bag than my GF. I have a 30° bag, hers is a 20°. Lastly, two separate bags offer more flexibility in the event that you need sleeping bags, but don't have room for a side-by-side arrangement.
