In reply to Reiverdale Boss:
Well it's basically two down top bags I guess - never going to be cheap.
We have a synthetic version and it is great for non-backpacking use - Mrs B loves it, especially teamed up with the down air mats. The best bet would be to get someone passing through the US to get one from REI, if you can manage it....
I'm not aware of anyone doing similar bags currently.
Cheers
