@WedaPashi the question was quite broad in terms of activity. But go for the one which suits best? Or leave without an accepted answer a while longer? Either way it was a good question!
@WedaPashi I think the problem is that the question is applicable to such a broad range of activities each of which use it differently. Maybe restrict it a bit more?
@Liam: I totally agree with you regarding the suggestion to restrict the scope a bit. But, now if I restrict it to Hiking, Mountaineering (which I do the most as compared to any other outdoor stuff) it will be unfair to @Aravona because her answer may no longer be applicable, and I'd hate to do that.
I want to go backpacking with a couple friends, but I'm the only one of us with any experience, and I mostly day hike. I've only done a couple of backpacking trips. They've never backpacked, and only hiked occasionally.
