Bought this as part of the Black Friday deal series from Amazon, and thus got it for around half-price. At that price, it's a very good deal indeed. The material it's made of (it's not leather-look except at a very quick glance, despite what the Amazon page says - it's brown nylon, the sort of thing good rucksacks are made from) is very high quality, and It's already been tested as being showerproof. Inside, there's lots of space, including two zipped pockets, a well padded pocket for a tablet or smallish laptop, and external zipped pockets (one on the front and one on the back). The whole thing seems really built to last, and I look forward to using it for years to come. The only very slight criticism I could make is that there's no real 'handle' on top, so it's a bit more difficult to just pick up and go than it could be. Also, the shoulder strap is a bit slippery, and is fixed, rather than removable - but these are very minor quibbles. Great bag, decent quality - just glad I didn't opt for the medium one!
