This is a pretty good back pack which I have now taken to Kenya twice. Its quite a large bag, I got it onto Virgin airlines ok but it was way over the hand luggage weight, when I weighed it fully packed it came to a shoulder straining 15 kilos! So yes it really can take a lot and you really do need the belt. Good points, very comfortable, fully adjustable, good space in the bottom section for a good sized SLR and up to 4 lenses and filters, also bottom padded section is removable - (I have taken this out and used it in a smaller standard packback), top section has good space for cables, and other junk, small packed lunch and lightweight jacket etc. Good fittings on the outside for attachments, monopods etc. Made of a durable material that I'm sure will last many years. Where it could improve; the item is made in China and I think sometimes goods manufactured there miss a bit of quality, this is evident in the zips, they are heavy duty but they don't open and close as smoothly as I would have liked, also the stitching that holds them to the bag could be better, I think they will last years but I would guess the first thing to break would be something to do with the zips. The two small pockets on the outside are almost pointless as is the side netting. The divider between the two compartments is removable and isn't quite as stiff as I would have liked. Overall a good bag but not for those with weak shoulders, loses a star due to zips and pointless pockets.
