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.
