A student I was teaching at University this last fortnight had one of these. I played with it loaded up with his study materials and was impressed.
On sale for $49.95 (right now that's about one french fry in the USA).
Unfortunately the weight is pretty up there at 440 grams (15.52oz) according to their spec. Could be trimmed down a couple of ounces I suppose. Has a removable back pad but I didn't notice that on my 10 second play with it.

I might pick one up and deconstruct it. It would make a good hack SUL bag for off track overnight jaunts here in Australia with that 220 Cordura.
