The insulating jacket is super light and has a reasonably small package. This is schonmal well. They isolated well and has a good size. However, the processing is not so good. One of the two sutures attached to hold the mat straps risen the first Curled direct. I will now have to sew. The material is also rather low and I can imagine that the aluminum detaches relatively quickly. For the price it's ok. I'll look around, however, by a somewhat higher quality replacement.
