It started out as a joke, and the joke created a demand. Thinkgeek is trying to produce a Tauntaun sleeping bag. I personally hope that they start to offer adult sizes for all us grown up geeks. I could fit in a 60 inch tall bag, but really I would hope for more room than that.

Definitely check out the thinkgeek page here, and you will have to appreciate the lining on the inside of the bag, a delightful little print of intestines, so you could almost approximate that feeling of being cuddled by intestine-y warmth. I suppose asking for life-like feeling goo to lube the intestines would be too gross.
