Has anyone tried the Osprey Momentum? I think it looks pretty well thought out for my needs, anyway:
Osprey Momentum 26
No experience with it, but noticed something interesting following your link. Click on the specs tab and you'll notice they have two sizes (S/M and M/L). Both have the same stated product dimensions...
If you can afford it, go right on ahead and get it. Then you can do a review of it here.
