Quoted By:
The last 3 multi-day treks through the mountains, with full pack, there was always that one guy who didn't bring poles.
The same guy who wore camo pants and heavy leather boots.
And on all 3 trips, it was that guy who I had to lend my poles to cause his knees hurt from doing 800-1000 m elevation both ways in one day (>oh yeah, I'm pretty fit I can handle it).
If you go into alpine territory, and you carry all you need to sleep outside on your back, you'd better bring poles. Even if you're 20.
Besides, they have a dozen other uses, pic related.
