>>1732653Right, a do-it-all *daypack*, what are you missing? You can't use an 60l bag for a 20l bag's job or vice versa, but you can have a 20l bag that can go to a meeting, the club, the trail, and the cliff, and you can have an 60l bag that hikes and climbs. I've also seen stuff that builds in a panel loading zip for travel-ish stuff, but I don't like that from a durability standpoint.
>ultralight garbageI'm not a partisan of ultralight for ultralight's sake. The most likely production fabric for a bag like this would be VX42, with a face fabric solidly in line with normal /out/ bags and a laminate and liner adding weight. But all those are extensively used by professionals and top athletes. Klattermusen also isn't ultralight; their rolltops have 400d pr 840d face fabrics and look like pic related. Cilogear and HMG are heavy duty *and* ultralight with the woven Dyneema fabrics.
>Different design requirementsExactly, and I'm imagining a bag that satisfies both. You don't see a clear through line between the Davis, the Mochilla, and the Outlier (built for bike commuting, but fancy)? When you pare things down to a simple, adaptable shape, you can make them do more.
>I don't think you've ever used woolDude, I'm wearing a wool baselayer tee now. It traps less shit than spacer mesh, and ime Power Wool traps less than most wool jersey.
Why don't you like rolltops? What does your ideal daypack look like?
