Comments about Adventure Medical Heatsheets Emergency Bivvy:
I just came back from a weekend in Joshua Tree National Park. We were only supposed to be out for a long day-hike but it turned into an unplanned overnight in the cold rocks. It got down to the mid 30's F at night and this bivvy kept us warm from the cold night air/wind. It developed a ton of condensation inside the bag but it was a toss up between being warm and moist inside the bag or cold and dry outside. There were nine of us out there and only one of these bivvy's and a couple space blankets...we took turns. The blanket tore quickly and kept flying up in the wind. But this bivvy doesn't lose heat to the wind and won't tear as easily as those blankets. I think everyone in the group is gonna go buy one of these for their daypack now.

Comments about Adventure Medical Heatsheets Emergency Bivvy:
My family always has one with us in any outdoor situation. I have used shelters like this in emergency situations twice. Once to help a guy with a broken leg stay out of shock and once to keep warm in in a freak ice storm. We used shelters just like this in the Infantry as sleeping bags along with our Ranger blankets to sleep in some pretty nasty weather. We made it OK and that proves to me their worth! My question to anyone is: why do you not have one?

Comments about Adventure Medical Heatsheets Emergency Bivvy:
I bought this emergency bivvy to carry with me on all my backpacking trips in case of a real emergency or to cover my sleeping bag with when I travel without a tent. I personally have never had to use it in either situation but my backpacking companion wanted to see what it was like on our last backpacking trip in the Tahoe National forest at the end of summer. He slept inside it with my thermolite sleeping bag liner (to add a layer of separation between him and the bivvy material). Although he said it kept him decently warm, a lot of water condensation formed inside the bivvy which got the liner wet and made it uncomfortable. I don't know if anyone else has experienced this, which is a definite drawback, but I still carry it with me because its much better than nothing or the typical space blanket in an emergency.

Comments about Adventure Medical Heatsheets Emergency Bivvy:
The bivy performed to specifications in a 31 degree river bottom in Northern California. I used it to maintain body temperature for an injured teammate during a Search and Rescue mission. The bivy exceeded my expectations in keeping my teammate warm during the early morning hours while we waited for an aerial medivac after dawn.
