I have found that much of the ultralight gear is strictly for people who make ultralight the raison d'etre of their activities. You have to be careful with it. It just doesn't stand up for rugged or even moderate regular use. I would not want to use it for emergency gear, where reliability is worth saving a few ounces (in a pack). What I mean is, separate ultralight from survival in anything that will take a bit of a beating.
