trailgear, I'm glad you've had good luck but mine was falling apart out of the package which in an emergency situation and never inspected because you trust a vendor of a good product could have resulted in a life threatening situation. I will give you credit this is better than nothing, but it has reinforced the fact that nothing beats a bag and bivy. All the noise that it makes and how fragile mine is, I would opt for a bag or poncho liner. To each is his own, I know the mylar and type materials have always had a shelf life break down period. I've changed out tons of mylar with Meximelt on aircraft due to static and desegregation. Even on aircraft, new it works great but very noisy but after a few years, noticeable desegregation occurs. If you inspect yours closely, do you have any small holes developing yet? If not, ma bey you got a good batch for now but time will tell. I still am very very dissatisfied with the quality. I would not put my life on it for sure.
