Man, that thing is really nifty. But I could never justify $100 for a sleeping bag, and one that is too small for me to use no less. Also, if I am not mistaken, it seems they are already sold out. I got my email from thinkgeek informing me they were not available, only to follow the link to see it cost $99.99 and was sold out. Must not have made very many, I think I remember the email saying the initial run would be limited. Hopefully more are on the way and will become cheaper eventually, but I wont hold my breath.
