This back pack is very comfy, with wide padded straps that are easily adjusted. There is an added strap across the front to give extra support when the pack is heavily laden.
There are plenty of compartments, ranging from the usual lap top pocket to a zip pocket on the bottom. There is a small zip compartment on the top, could be useful for a travel card, and a large stationary pocket on the front. I admit I blow hot and cold over the drawstring sleeve at the opening to the main storage area, at first it seemed like a bit of a bind, but having used it on a wet day, on a crowded train I appreciated the protection and potential added security it gave me.
Its a good size and would easily pass as cabin baggage on some of our fussier budget airlines. It was also roomy enough to take, amongst other thing, a hard hat!
My only slight reservations are, that the side pockets have zips, and are not open, so not too useful for the ubiquitous water bottle. And I think its a little over priced, by ten pounds or so. However, its a good looking, comfy, practical bag. Better than a lot on the market.
