Based on my experience Black Diamond has the best lightweight harnesses right now. I use the Zone for everything and have had it since 2018 - still in great shape and showing no serious wear despite many long routes and granite chimneys etc. You can get a triple rack on it. Very hard to beat IMO and I’ve also never had to warranty a BD harness (I work for Bergfreunde so we sell a large number). Petzl/mammut/WC seem to get trashed easily.
