OK, let's deal with the size of this bag. If your laptop is bigger than 39cm x 27cm x 5cm then your going to struggle to fit it in. I'd regard these measurements as the limit. The laptop compartment is very well padded and so I really wouldn't bother with a sleeve and it's also red inside, a nice touch. Inside, in addition to the padded laptop compartment, there are three open pockets, one measuring 40x20 (suitable for an A4 pad) and two at 15x20 that will fit a mouse etc. There is also a zipped compartment measuring 32x9 and a couple of business card size pockets. There's also sufficient room for the power supply in here and a separate nylon `pencil' case is supplied for this(very handy).
On the outside of the case there's a zipped pocket measuring 30 wide x 20 deep with a pocket inside and a further zipped compartment on the front 15x25. I'm not sure how handy this one is, you could only really get thin items in it. Finally there is an open pocket with a Velcro seal measuring 40x25 that can be used to hide the shoulder strap and/or carry a thin A4 binder.
The bag is very neat and very well made; the crimson interior and trimmings are a nice touch and makes this bag slightly unusual. The handle is wide, secure and slightly padded making it comfortable to carry, even when it's fully loaded. The shoulder strap is wide enough to spread the load and won't cut into your shoulder and a really nice feature is the way that is can be stowed in the pocket when not in use (although it cannot be detached from the bag).
The bag isn't as capacious as some and if you `live' out of your laptop bag then this probably isn't the one for you. But if you need a stylish bag that's easy to carry, neat and well made, then for the price you really won't do better than this one. I can highly recommend it.
