Just 10 years ago (Or 5, or 15!) the UL backpacking landscape looked very different than it does today. In fact, when I look through old posts of this site I can see some people using some very different kit! It seems that there was an entire range of UL ideas, some of which are still common, but some of which seem to have fallen out of favor with today's posters and hikers.
e.g. When I was first thinking about this topic, I was thinking of extra socks. Some older style bags and some DIY kits left little pockets on the inside of your shoulder straps where you could stuff your extra socks with the idea being to multiuse them as padding! Ingenious idea! But I don't commonly see this practice recommended any longer, nor do I see cottage companies providing those little pockets on their packs any more. Who would have guessed that jamming stinky old socks 4 inches under your nose wouldn't be an everlasting idea!
e.g.2 Spinnaker fabric. I don't think this was ever as seriously touted as silicone impregnated nylon, but it was offered in a number of products. I guess it just proved to be too delicate and not as desirable as cuben.
e.g.3 Packs without waist straps. I know this was a Jardine idea, and I've seen it suggested that his history as a rock climber gave him enough upper body musculature to get away with this idea, but that not everyone could. Heck, even companies like MLD have a padded hipbelt on their smallest packs by default. So what happened to the waistbelt-less pack? Only the craziest of the SUL guys seem to go that route anymore.
What are some other UL ideas that just haven't seemed to catch on and continue to be common in current use?
