Lowe Alpine do make some really well-specced medium capacity packs, and this could well be another. I've somehow acquired four (

) in the last few years, all with variations of the Adaptive Fit harness and they do carry very comfortably. They're also well designed with features that genuinely work, although (with the exception of the Zepton 50) it does tend to add a few extra grams, so keeping this Alpine Attack 35:45 light and strippable seems like a welcome development.
Not sure about the "Headlocker" system though. It looks like it'll work well for weird shaped technical axes, but it potentially limits the pack's versatility - not likely to be so good sharing one central attachment bar for more traditional axes, and no use at all for carrying poles, shovel handle, etc.
