Awesome. Pack. Hope it never dies.
My goal was to buy a pack that works for a day hike and works for the commute. The 28L size works great- I can stuff my workout clothes + lunch + laptop in when I head into the lab. The laptop container does truly convert to a camelback container and after a week of long day hikes in 40-70 degrees, I have decided this is an awesome day hike bag as well. It allows you to carry enough food + layers for a variety of conditions. When it's not as full, it cinches down well. It's an added plus that the cinch down straps can help keep your nalgenes in if you have them on the sides. I find it very comfortable. Haven't tried the keep dry front pocket yet.
I don't know if I would recommend this for someone with a small torso or a very petite person. But other than that it's darn near perfect, I agree with the others, and I would buy this all over again.
