I've owned the Osprey Kestrel (early model) and Finesse (w/ Vector Two) and used the Isis: all great packs for a small woman (5'2"). Superb quality, very balanced (you can forget you've got a pack on). The Vector II is a great innovation, and more than makes up for the paucity of pockets.
Quite simply put, this pack is a top-notch performer.

Quite simply put, this pack is a top-notch performer. It is rugged, agile, and adept at handling a variety of load considerations; to these ends, I use the Finesse to carry all of my photography gear (large tripod tethered to the side), all of my regular Rocky Mountain day gear and it still has just enough room for my lunch, without crushing my crackers!
So impressed was I that I recommended it to a friend, who, upon talking with the salesman at a local, trusted outdoor retailer, decided to purchase the Finesse Pro.
Osprey has included such additions as their "Vector" system of interchangeable attachments allowing for various sorts of pack-volume additions as well as specialty attachments such as their "Vector Snow/Ice" that allows for better crampon attachment and the "Vector Chair," which is actually a folding camp chair that, like the other Vector additions, attaches to the rear of the pack via quick-releases. The Vector system, along with several, well placed compression straps, help this pack hand all your gear extremely well.
With any overexagerations aside and as my above "novel" should imply, this is a great pack for those who like flexibility in pack loads, durability, and comfort all in a nice, tidy package.
Note: make sure you spend enough time at the store or on your own making sure the pack's aluminium stay matches your back's curves, if not, it won't make any difference how well designed this pack is.
This is by far the most comfortable pack I've ever…

This is by far the most comfortable pack I've ever owned or worn. A great daypack! I added the Osprey Vector Ice attachment ($38) for my crampons and am currently using the pack on all of my ice climbing day trips. It swallows everything I need for these trips and cinches down TIGHT. Simply a fabulous pack. I plan to add a couple of other Osprey attachments (Map Wrap, Quick Click Holster and Aqua Holster) this summer to make this a great summer daytrip pack. I can't wait!
