Yeah, obviously that's an expensive option but someone who spends a lot of time in on the highway in the winter or say a Canadian bush pilot might find it a lifesaver. You could get one behind the seat of a truck were you couldn't fit a regular bag, for instance.

I don't have one of the vacuumed bags but I don't rule out getting one eventually. I have two Wigggy's bags and can't say enough about the quality.
