Tyvek has its uses fo4 camp and hunting, but it is not perfect. It is tough, light weight, relatively cheap, loud until washed multiple times, comes in big chunks, and is bulky. It is like most items out there, a lot of pros n cons to weigh out for your personal preference.
I have a chunk for just in case and won’t feel bad if I need to cut it up or pitch it near a fire and risk pinholes.
