Since the opportunity arose to evaluate and review Adventure Medical Kits (AMK) new Heatsheet Emergency Bivvy. For those of you that aren't familiar with AMK's Heatsheet, they are the latest in space blanket technology. Doug has a quick review here, but basically the Heatsheet utilizes a new material, replacing the brittle and noisy traditional Mylar material with a "special low-density polyethylene film." AMK printed one side with an orange background and survival instructions giving added function to the Heatsheet. A major benefit of this polyethylene material is that when it tears it doesn't shred, if a hole should occur it can easily be repaired with a piece of duct tape or by simply tying a knot in the material to occlude the hole. These new space blankets are much quieter, stronger and more versatile then the old Mylar blankets.

In the Heatsheet Emergency Bivvy AMK takes the concept of theirThermo-Lite( you can read my test of this exceptional product here ) and combines it with this new material. The end product is a lighter and smaller Bivvy sack for emergency kits.

My initial test of the Heatsheet Emergency Bivvy was in less severe conditions then my test of the Thermo-Lite Bivvy. I plan on doing a few more tests in different conditions but the night of this test the temperature dropped only to 52deg F. I used the Bivvy alone with no shelter or fire and I slept in a cotton long-sleeve t-shirt and cotton utility pants as well as wool hiking socks. It was about 58deg F when I went to bed, and dropped to 52deg F in the four hours I was in the Bivvy. While these conditions are far from cold, I was completely warm inside the Bivvy. The Heatsheet Emergency Bivvy was as warm, if not warmer then the Thermo-Lite Bivvy in similar conditions, however it blocked the wind much better!

I plan on using the Heatsheet Emergency Bivvy in all of the kits I currently have a Thermo-Lite Bivvy in and a few of my kits that I currently have a Heatsheet in. The Heatsheet Emergency Bivvy is close to a quarter the size of the Thermo-Lite Bivvy but is bulkier and takes up a little more then twice the space of the standard 2-Person Heatsheet.

The small sack it comes in is slightly oversized, which allows you to keep additional survival items in it. I was able to fit 20' of 550 cord, one of Doug Ritter's AMK Pocket Survival Pack, Doug Ritter Special Edition eQ Hands-Free Multi-Light , 10 Katadyn Micropur water purification tablets and 6 Gerber Breast Milk bags. This setup was a little bigger then I would like to carry in my pocket, but it makes an almost idea survival kit for backpacking or in a Camelbak for day hikes.

For some reason the whole review would not post in a single post. I have no idea why, but sorry for the multiple posts.

I actually noticed no condensation, it was not very humid and I condensation is greatly reduced by not exhauling into a sleeping bag.

Where can we buy the bivy from?

The links I keep finding are only the blanket...

When you used the bivvy, did you have some sort of insulation from the ground? Did you sleep on cement, wood, grass?
