Don't discount multi-day capabilities
This is not just an overnight pack. I'm surprised to find no reviews talking about the Axios' excellent multi-day credentials. So, I'm adding mine.
Not sure what catagory I'm in: somewhat light packer, light packer, probably not ultra-light or mega-superduper light. I can tell you this, I carry a lot less than I used to. This pack was my move away from using a Bora 80 on summer trips.
I've been on a pair of five day/four night summer trips into the high Sierra with the Axios 50, and I was mightily impressed. At the start of each trip, total pack weight was around 32-33 pounds, which I would offer is the most I could carry with this pack before the waistbelt starts to lose the battle against the shoulder straps. It's the only thing I would have loved to see: just a slightly beefier waistbelt. It's a very minor quibble.
By morning of Day 2 and a pair of big meals later, this pack came into its own. It shines at around 30 pounds or less, in my humble opinion.
In my Axios (I have the Tall), I can easily fit my MH Phantom 32, ProLite 4, half of a Hubba Hubba, cookset/stove/fuel, Crazy Creek chair (guilty pleasure), 2 liter bladder, clothing and food.
For shorter shoulder season trips, 2-3 nights, I can still take this pack. Warmer clothing and bag are the only changes I make.
