Weighing 9 pounds, and measuring 11.8W x 5.1D x 15.6H inches, this utilitarian camera bag is packed full of useful features for photographers. Inside it has a padded and protective divider system that has velcro adjustments so that you can align the dividers to best meet the needs of your equipment. Lowepro say that it will fit a DSLR with an attached 70-200mm f/2.8 plus 3-4 lenses or flash accessories. In my test, it easily accommodated my Nikon D90 with 55-200mm lens attached, an 18-55mm, a 50mm f/1.8, my Metz 48 AF-1, a battery charger, various filters, spare batteries, and a Lightsphere Collapsible.
In the front pocket there is a padded neoprene laptop sleeve, which will hold laptops up to 15.4 inches. To me this seems a little strange when 15.6 inches is becoming a popular standard size. I tried to squeeze my 15.6 inch Acer into the sleeve but as per the spec sheet, there just wasn't room. MacBook users will doubtless have few problems with this, while netbooks and 14-inch notebooks will also be fine, but wouldn't it have been nice to have allowed an extra half inch or so to appeal to a wider variety of laptop users? The next model up in this range, the x450, has more room and allows for laptops up to 17 inches, so consider that if you need the extra space for a larger laptop.
Externally there are straps for attaching a tripod or monopod, two replaceable wheels, a telescopic handle, and numerous adjustable padded straps for carrying and using as a backpack. The straps tuck away when they are not needed, but are quick to find when you need to make the change from rolling bag to backpack. There is even a handy built-in all-weather cover tucked away behind a flap underneath the bag. Pull it out and it will cover the entire case and add some additional weather protection when you most need it.
