Okay so I finally got to look at a Flash 45 in person today…
I officially take back everything good I've ever said about this pack. From the specs I'd assumed it would have a somewhat stiff frame. It does not. The "frame" is barely stiffer then the foam back panel on a Golite Jam. This is not the breakthrough design I'd hoped for. If you like the current Jam you might like the REI but its not a true internal frame pack.
What a disappointment I was thinking we had a $140 pack that weighed 2 pounds and could actually carry some weight.
