Almost all of my backpacking is with another person so a 2-3 person tent is used for such excursions. I'm looking to get a tent/tarp/tt to bring with me when I hike alone, which is most of the time.
The purpose of this shelter would be for use in the event I twist an ankle or break a leg. I want something that I can use for survival purposes. Consequently, the shelter will have very little, or no, use. Therefore, while I do want to go ultralight, I don't want to drop a lot of money on it.
The TT Sublite (tyvek) seems to fit the bill at <20oz and $179. So does the Contrail although it is heavier and $20 more. It would be used in the Adirondacks where it is wet, and teeming with bugs, so I wouldn't normally consider the Sublite for general purpose use there. However, as a survival tent it seems to work.
Any thoughts?
