I looked at the official posting for the two new "Flight" series packs. The Flight 30, a 15oz 1900 cu in pack is just too heavy for me and will likely be for anyone aiming for anything approaching SUL base weight. For my hiking purposes the vest harness is also plain gimmicky. My Zimmerbuilt Quickstep is the same volume, is 9.4oz and, fully loaded with my SUL kit, it is almost like I am not wearing a pack. I can add a pack lid and two shoulder pouches and still be a couple ounces lighter then the Flight 30 with plenty of organization and storage.
The Flight 40, at 2600 cu in and 31 oz, is pretty heavy for my taste. For comparison, it is 3oz heavier then the HMG Windrider 2400. I do like that it can be stripped down to 18oz, but that is still pretty heavy for a UL pack with 2600 cu in of volume.
I see the "gram weenie" bashing and all this talk of "comfort." I have found less weight has corresponded to more comfort for me, not less. Back in my 20's, when I was heavy hauler, my Dana Designs Arcflex Terraplane could make 50 lbs ride comfortably. However, it was still 50 lbs freaking pounds, no matter how well distributed and padded the weight was. I have never been uncomfortable with my frameless packs. With a GG Nighlight in the pad sleeve of my Mariposa, with a properly packed and distributed load, I have never had a problem even well into the mid 20 pound range. I have found just the opposite in fact, I have never hiked as comfortably or as far in my life when I have gotten my base weight down. If I ever need to haul gallons of water for days, moose hind quarters, or gold mining equipment I will reconsider.
I won't be following the herd to heavier packs, even if that is where the market is lumbering. I re-read Ron's blog post about the "death of ultralight" and maybe he just doing his part and making some money along the way. I wish SMD luck. My money is still on UL and SUL. Via La UL Revolucion!
