Firstly, the quality of materials used, is exceptionally high. Its tough, well padded and the zips are good quality and sturdy. This is the black one and ig looks reasonably stylish, with its compact design and orange detailing.The upper compartment has a top access zip. This zip is not protected in any way. This provides a potential leak point without an additional waterproof cover. Thankfully a rain cover is supplied, so thats taken care of. This section isn't large in any way, however is big enough for a couple of decent sandwiches or so on! The base of the upper compartment is however removable by way of hook and loop tape, allowing it to easily open up into one larger section.The base compartment has two access points. One against your back, for general access to the entire lower section and the one on the side, allowing quick access to your camera only. There are deviders supplied for this lower section and these are attached via hook and loop strips.Additionally to the above, there is an unpadded zipped compartment on the face side and a small external mesh side pocket. On the face side, are two webbing straps to hold a compact tripod and a grab handle positioned between them.Now to the actual review itself. The bag is very compact and the lower section is just large enough to squeeze in my Canon 750d with 50mm prime fitted, an 18-55mm kit lens and a 75-300mm zoom in the lower compartment. Now by "squeeze", what I mean is that I can shoehorn them in, just! Now remember that you can remove that divider and make it into one larger bag! The side access port has two small elastic pockets attached.The upper compartment contains two mesh pockets. These are just the right size for a filter or two, a couple of spare batteries and some SD Cards.Pro's:Compact, light weight, good quality, stylish.Cons:The base section is bit too small to carry the average dslr users kit. Accept that you will have to leave a lens or two at home or use the upper section fir storing kit and buy your food when you need it. It would probably be ideal for a Mirrorless or compact system user though.The tripod straps are well fitted, however even a modest tripod causes some access issues to the top comparment. The access zip would have been better relocated to the rear of the bag, just below the shoulder strap.The hook and loop tape is not strong enough and detaches too easily. The poitioning of the tape isn't ideal, as layout options are very limited. The lower section should have been lined with loop or a compatable fleece material and the dividers should have been a touch larger!The zipped compartment intended for a tablet device isn't protected by padding. This makes the tablet vulnerable to knocks, however it is also subject to weight stress caused by the positioning of a tripod! This wouldn't be a major problem, however my 7 inch Samsung Galaxy Tab S2, is a tight fit with a thin silicone cover attached, so extra vulnerable!The bottom line is that this bag is a very good quality for the price. If you can live with some compromise, then it's really good value for money. If you need to carry more gear, then you should consider buying the larger version, however you really have do pay for the extra capacity!
