This is a nice bag, seems very well made. The design is a little different than most, feeling more like a bag with a zipper around the lid area than the traditional backpack. The organizer pocket looks awesome and the bag seems like it would hold up as well as anything else I've had. The problem is I bought this for my wife and it's way too tall. She is on the short side, but I tried it on around the house and the way the straps are set up, it feels much taller than average to me as well (6'1"). If you're tall and/or have a long torso, it would probably be a great bag for you. Since it was for my wife (I would have kept it except I already have too many backpacks), it got returned.

There should be something about the size in the description somewhere, but there's not.

Fantastic top, regardless of the activity! Keeps me just warm enough when it's cool out, and manages warm temps better than any other base layer I've had. (Which is to say it beats 5 or 6 other big names.) Perfect for layering under my softshell. Fit is a touch on the snug side, as it should be for a wicking base layer. At 6'1", 185 lbs, a medium is just the right length in the arms and the torso, neck fits good, and it has a nice long zip for when I want some extra ventilation. Chest pocket is nice too. Really, the only place I don't like the fit is around my belly, which could use a bit of work anyway :) Does seem a bit likely to snag, but I haven't had that problem yet. All things considered, I'm not sure I'll ever buy anything else.
