Enough specifications here, so I will concentrate on a few points I like about this bag. First of all, with the image here you may get an impression that this is a fairly big bag, but in fact it's a tiny little one. Just about the size of a modern HDD camcorder.
My camcorder is a SONY DVD one, and it was slightly too big for the bag, so I had to remove the padded compartment divider in it, and now it fits perfectly! If you have a middle-sized digital camera, an iPod or any (not too big) electric devices, this bag will be very useful to either carry them around or to simply store them when you're not using them.
This bag also has a number of small pockets, so you could also carry your extra memory cards, an extra battery or even an OysterCard etct etc. It comes with a shoulder strap so you could carry it like a shoulder bag, but you can also attach it to your belt, so if you wear it around your waist, both your hands are free, which is nice as carrying a camcorder or a camera can be heavy! You could also put some valuables during a flight, e.g. your passport, so it would be a useful bag in many ways! I'm already loving it!
