(Edit: 12:30PM woot time: It looks like woot and imgur aren't playing well right now, so I put the images in an imgur album; they're in order of description below.)
Women's versus men's pack: I believe the suspensions are shaped differently; I tried both packs on and noticed a difference in the feel when they had ~10 pounds in it. I'm small and have back problems, but it was enough of a difference that I was willing to pay $15 more for the women's pack, which I don't regret. Well, until I saw this price. (I bought mine in October 2010 and have gotten good use out of it, so I don't regret it per se, but this is definitely an amazing price. It's such a good deal that I kinda want to buy another one, except that Kelty packs never die, so I have no use for it!)
As I was climbing into bed, I saw my Avocet 30 on the bookshelf and thought, hmm, I wonder if it's larger than a pillow.
I'd say that it's the same height, almost exactly, but the pillow is several inches wider.
And as long as I had it out, might as well augment woot's pictures with the angles that they don't show. The back:
bottom to top:
hip belt: fully adjustable (it should be wore around the belly button for best results; I grabbed a measuring tape: over my PJs, my waist is between 24-25" and this adjusts to that, but I've also worn it over a winter parka and adjusted it over that comfortably); however, the hip belt isn't padded.
shoulder straps, bottom: like any good pack, the length of the shoulder straps is easily adjustable after you've put it on by grabbing the ends and pulling
sternum strap: if you look closely, you can see that it slides along a little track, so you can position it higher or lower, depending on what's comfortable for you. It adjusts in width, of course. (BTW, I popped it out of the little track once and was able to put it back in with some effort); I just noticed that there's a little loop on it; could easily put something light on a carabiner
handle: there's a handle
shoulder straps, top: again, like a high-quality pack, totally adjustable
tie-down straps: you can't really see it here, but the straps holding down the hood are also adjustable in order to compress the load as much as possible - which also makes it steadier and less prone to sway if you're riding a bike. Or limping through an airport on crutches trying to make your connection that leaves in 30 seconds.
Hood has a pocket with a little keychain thing. For air travel, this pocket suffices for me to hold boarding pass, map, cell phone, etc.
Bad photo of the interior: there's a flat pocket against the back that I find useful for my laptop or a folder of papers that I don't want bent; there's not much give to the pocket, which makes it nice to hold a laptop in the right position weight-wise, but I'm not sure if it would accommodate the depth of a larger laptop. There's the strap above it with the teeny plastic carabiners.
Pack pulls shut with a drawstring, which I then tuck inside the pack, close the front hook, and start tightening straps. The side compression straps are great.
I've attached a water bottle via carabiner to the daisy chain. On one occasion, the cheap water bottle cap broke, but generally, it works fine - although it can get some side-to-side momentum going. Kelty says it holds an ice pick; I must admit that I've never tried. I'm a backpacker, not a hiker, but I've used this both for backpacking and for trips to the store when I'm walking/biking.
Sorry for the blurriness of some of the pictures; it's dark-o'clock and I really need to be in bed, but I hope this more-detailed tour of the pack is helpful to someone. I didn't understand most of these features until the nice folks at REI walked me through them, plus it's hard to fully appreciate the quality/features/awesomeness of the pack unless you're holding it, so I wanted to pay that forward, especially to others who are new to backpacking/hiking packs like I was two years ago.
