Timing is everything. I just returned from an overnight trip into the mountains above Edwards AFB in the desert and a fresh snowfall. I had this unit, my Wiggys and a 4'x6' semi antique persian rug ( i'll explain later.) I'm not a big fan of space blankets in general. They are hyped because of their use by NASA. Modern space suits long ago abandoned the concept. They are usefull simply on a 'better than nothing' philosophy, are very compact and make excellent reflexive surfaces in a shelter to maximise a campfire's efficiency.Those are my personal appraisals. This unit is well made. The cellular construction provides some insulation, emphasis on some. It does drape well and was a terrific wind barrier. This is probably the #1 desired feature of a blizzard bag anyway. Like any sleeping bag the cells crush down where you contact the ground. I had this persian rug and it provided an excellent ground pad. I was also dressed in my Filsons. With this combination the bag proved an efficient, though expensive bag that met my expectations of a onetime use emergency unit. I did quickly climb into my Wiggy's. With deliberation I managed to refold the unit into a semblence of disorder. In an emergency situation it would survive the rigeurs of repeat use with care. If space is a consideration, onetime use or price not an issue, I would give it a thumbs up. If you can manage a bulkier unit get a bag. My exotic groundpad was deliberately turned upside down in the fresh snowfall. This is the traditional cleaning method. When I packed up I left a bit more than the no impact footprint.
