Came across the ICEBOX Igloo maker while surfing some sites.

Looks like you would need to make several practice igloos after reading instructions and watching the DVD but I'm thinking this would be useful to toss into the vehicle for SHTF. Would take a couple hours to build an igloo based on what I've been reading but still, would be a good shelter/option to have in the winter. Not a quick emergency tool but a survival tool. At $170 it's not cheap but can build a durable shelter in a couple hours...
