I tried a Dyneema liner. Did not complete a thru hike before it was wicking water from my backpack inside the liner into my sleeping bag.
I’m now using Nylofume. It only costs $2.50. And I can tell when it isn’t waterproof without having to use the “wet sleeping bag” test.
Otherwise, this is finally out. https://www.halfwayanywhere.com/trails/pacific-crest-trail/pct-gear-guide-2023/
My Moabs are 40.5 European. The Topos are size 43 Ultraventure low tops. 10.5 vs 17.6 each. I’m getting used to them but they work.
The Ultra Raptors are 13.5 ounces each and European 41.5.
I’m liking the Topos and hope that they are comfortable with a full pack for longer distances—so far the longest distance with a full pack was ~4.5 miles or so.
