I have the have the older version of the Duplex. I have been really happy with it so far. I haven't used anything else from Zpack except their stuff sacks.
The first 2 are my go to for dailyhikes thru 5 day backpacking, depending on the season, and then I have the third for mega hauls. Now that Lucky is bigger, He also carries more in his backpack too, which lightens my load because I used to carry all of his stuff and he is quite spoiled.
