Rated 4 out of 5 by from weighs very little, takes up no space, An essential survival tool summer or winter. Takes up little space, weighs almost nothing. If you want, buy two and try one out first to get the hang of it. Better yet, just buy one & if you end up really needing to use it, you'll figure it out in a hurry. Keeps you amazingly warm (but steamy). Feet may get cold so watch for frostbite. Not a substitute for proper gear, but WAY better than nothing.

Rated 5 out of 5 by from Works Great Took it up to whitney for a 20 hour summit. At about 5 AM altitude sickness kicked in as well as calorie deficiency. Could not get warm even while moving. Pulled over and took out blanket. Hard to open and hard to get in with hiking shoes. Immediately felt heat radiating of the inside wall. Got warm and continued. Worked well. Temps were around 30F.
