I don't understand the utility of these type of kits. If I'm going camping or backpacking I have good gear for the situation, as do most experienced adventureres. Even on a day hike, I have at least the basics with me. And when I say basics, I mean I could survive for a few days (not comfortably, but I'd be OK). I can't see a scenario where I'd carry just this in my pocket and head out anywhere where it would come in handy. I guess it's a mindset and preference. If you like to go super light and shove this in a pocket and head out, more power to you. Maybe long distance trail running?
