The Canon is exceptional … and exceptionally expensive. Its zippered Adjustable Thermo Gills lets body heat vent out without letting cold air in. The Stove Pipe Tunnel Hood limits how exposed your face is to the cold without hampering your breathing. And you can slide your hands through the zippered armholes so you can wear the Canon like a vest; eat chow, grab items, or close the main zipper without climbing out of this mummy bag. Comes with both storage bag and stuff sack.

Pros: A brilliant, user-friendly design that lets you regulate your temperature with ease, Smart engineering combined with outstanding materials, including a DWR-coated shell, If you feel cold in this, you either have no clue how to operate a zipper or you were a cadaver to begin with.

Cons: A Glock 43, a handheld Garmin GPS unit, and two weeks' worth of MREs — all cheaper than this sleeping bag. Combined. This one's financially unfeasible for all but the most affluent of preppers.
