When I started backpacking, the one of the main – and critical issues was what gear would be left behind. At that time, backpacks were heavy, external frame affairs, and it was common to see even experienced backpackers with sleeping pads, metal canteens, and heavy and bulky sleeping bags lashed or strapped to various places on the backpack. This was before the rise of synthetic materials, and the ultralight movement that has come to dominate not only backpacking, but the outdoor industry as a whole. When I look back on the gear that I and many other people used to carry, I realize that it truly was the dark ages in terms of how the sport has evolved.
