Having bought a new MacBookPro, I wanted to buy a backpack which protected it, but also gave sufficient space to take papers and other items required on business trips.
This Belkin pack fits the bill perfectly.
First, it is well padded externally and there is an additional internal section of padding where the laptop sits.
Second, there are a variety of pockets internal and external some zipped and some not which can hold leads and other peripherals or whatever you need to take.
Third, there is a long removable "pencil case" partly padded which could be for pencils, pens, etc, or to hold peripherals.
Fourth, it is REALLY comfortable to wear. The straps are padded and adjustable and I was able to wear this on a recent trip to London one shoulder. I did a fair amount of walking and didn't realise I was carrying anything. Tighten the strap to the desired level and there is no or only an absolute minimal of slippage and having to readjust.
And no, I don't work for Belkin and this is the first review I've written. I always do a great deal of research before buying anything and my research when selecting this product certainly proved to be true.
