In the 70's, most pack companies began with climbers and hikers making prototypes of what they themselves found truly useful and dependable. A lot of that was going on right here locally. You had packs by Jansport, Lowe, Kelty, seriously thought out and built domestically under the company oversight of the actual individuals. But now nearly everything is outsourced, made in quantity, and then potentially tweaked only after a lot of negative feedback in some particular or another. If I had a problem with a Sierra Designs tent, for example, I just walked across the RR tracks from my office and talked to the designer (who now, long retired, lives in my neighborhood). If it was North Face, a ten minute drive away (and I'm talking about the real deal North Face, not its "factory outlet" import stuff like today). Marmot was headquartered nearby. Eventually a backpacking and photography pal of mine bought the entire Sierra Designs facility. If I needed a pack modified, there was and still is a specialty shop in town, who even made my black Goretex dark cloths. So many things have changed. Now it's all about mass retailing.
