Well thought out and made backpack, all the stitching and fastenings look well done, should stand up to a bit of use. The fabric material is robust looking. There is a rain cover if required

The main compartment opens from the back of the pack, like a conventional back pack, some camera backpacks open from the strap side, with the idea being you can lay it on the ground and any dirt is not then transferred to your clothes.

My OM5 mk II fits easily with a 12-200mm lenses attached, leaving room (using the adjustable Velcro dividers) for a 12-45mm & 30mm macro lenses and a flash, with strap and spare battery pouch providing some additional padding. There is room, depending on requirements, for additional lenses when I acquire them, my 360 camera, or my smaller compact camera, or larger cleaning kit.

The zip up pockets in the lid has room for more spare batteries and the charger, along with other miscellaneous leads, cleaning tools etc

With the Velcro dividers there are other options available, being easy to reconfigure the space.

The padding on the straps and the mesh back is good for comfort, while the addition of a trolley handle strap helps with handling baggage in the airport. The side pockets allow for a water bottle and tripod, the water bottle holder took my insulated water bottle fairly easily, would also take a reasonable sized umbrella

The tag on the bag does refer to a chest strap, clarified as not on all bags, as I like a chest strap have ordered one to attach to the straps.

A good sized bag, for camera equipment and also could be used as a day pack if required, good for taking a wide variety of camera equipment, without being too large in itself, though have a smaller soft case for day to day use with just the basics.

I rate K & F Concepts as a manufacturer, having some of their filters, cleaning kits, chargers, batteries and other kit; they make good products at a reasonable price.
