Mylar Science Purchase Emergency Thermal Blankets 5 Pack

This blanket came in handy during our recent camping trip up north. The weather turned out to be colder than what we expected. You won’t be able to fold it up nice and neat after using it but it was pretty durable. I folded it as small as i can and stuck it inside my sleeping bag in case if I need it next time. Will most likely buy again if I run out.

Ready to first aid.

Good bang for the buck

Each blanket is individually wrapped, and folded nice and tight. 5 of them weigh quite a bit more then I expected. Unfortunately I do not have the means for an official measurement of weight. If you are super weight conscious in your BOB, I would not pack extras - only one for each person. I have a camping trip planned in a few weeks. Fall temps in WI can be unpredictable, but it is possible to hit zero overnight. Most likely, low 30's. I will use one of these for at least one night and report back. I update all my reviews as need be. 9.23.15***UPDATE*** I took one of these camping, and did devote one entire night to it. Keep in mind I had a tarp on the ground, tent on the tarp, and slept on top of my sleeping bag. When I went to bed I was all ready toasty warm from the fire and brandy, the temp was mid 50's (F). By first light, it was down to 36. I was PLENTY warm. BUT - this thing is noisy! Crinklecrinklecrinkle!!! Also, because it has no weight to it, you have to keep in tucked under your body to prevent cold air from creeping underneath it. However - neither of these complaints can be held against it as this is for survival. I am confident this would aide in my survival, and I would be glad I had it. It would certainly suffice until the fire is lit, shelter is built, better materials are found, etc....

They are very low cost and hopefully will help block the warm air from using the chimney effect of the stairway keeping the first floor warmer. Updating from yesterday...these blankets worked very well keeping the warm air downstairs and the difference between the two areas is remarkable. We put one blanket from the top of the staircase and brought it down the handrails and secured it snugly on the bottom edge and then hung another one over the top of the stairwell to hang down to the stairs. My cat can easily duck under and go where she wants and the expensive warm air stays down. We used four of the sheets and have a spare, but the sheets are surprisingly durable.
