I have a Maxpedition Fatboy shoulder bag (read: tactical man purse

)
for a year. It has held up nicely and seems to be a made well too.
I just bought this Mountainsmith back pack. It is the Approach ll.
2500ci. While not as big as the Becker it holds a bunch. May fill your niche for a smaller pack.
The axe pictured with it is a GB Sm Forest, 19" handle for scale.
There are outer side pockets, hydro pocket, rear pocket with mesh key pocket inside of it. And the neatest feature is the space/open pocket between the main bag and the outer pocket. Great for a poncho, sweater or maybe bike helmet.
Multi adustable (thick) waist and shoulder straps. Internal sheet frame with wire hoop.
I haven't hiked with it yet. Used it for luggage on a car camp and took it for a short walk while loaded with all sorts of sharp and pointy (read: heavy) stuff.
Seems like a winner to me. It's available at the big name shops, REI, EMS, Campmoor etc.
Hope it helps.
