I was most impressed at the portion 2:17-2:28 of the clip in the testing of the maneuverability, durability and comfort of the pack. Very impressive results indeed. I don't think the back pain side effect would last all that long or at least the pain would perhaps be more dispersed from my viewing of that part of the test section.
I know it has been a while and there has been a lot of discussion lately of the Bikini frame and the HighCamp bags. I still don't know. Last year after changing over to a Duplex frame, DT1 and DT3 bags, cargo panel, etc... The voices in my head kept telling me I made a mistake and I should have gone with the Flextrek 37 Trillion. Especially since Archwood offers professional training and has the CLIC adjustment system.
