I have just taken delivery of this backpack and transferred all of my gear into it. Canon SLR + wide angle lens, 2 x long zoom lens, 1 x short zoom, 1 x converter and a pack of close up filters. All fitted into the compartment section with a little room to spare, so very generous. The rest of the gear all fitted into the other compartments (and there was a fair amount). So far so good. The bag looks nice and feels good quality, the zips appear ok. The strap fasteners are plastic and look reasonably durable. However, and this is where it scored only 3 stars, I am a big bloke, 16st and 6ft tall. The straps, even when let out fully, just about fitted me around the shoulders and waist even over a T shirt. As a result, the chest strap fitted just below neck height, although I would probably never use it so I'm not too bothered. It may be a struggle to get comfortable if fitted over a, say, fleece coat. So buyers beware, if you are on the tad 'generous' side this backpack may not be big enough to fit you. Other than that the rucksack looks and performs really well and appears to be good value for money.
