Overall this is a pretty good evolution from the Airborne line that I'd bought this to replace. The redesign of the pack body areas allow it to hug your body more without cinch straps and the gen 2 harness allows the use of the gen 2 USWE GoPro harness which isn't as large and obtrusive to your upper body. The backpanel breathes better than those on the Airborne, so you don't feel as gross after a ride on a hot day, and it dries faster as well.
The one downside this has over the Airborne line is the loss of any organizer pouches in the center section where the reservoir sits. It also still lacks a key clip, which I'd like to see USWE add...I honestly don't know why they still haven't added this, like all other mainline hydration packs have had for years.
