I opted for this after reading some of the reviews on the Snukpak bag that is similar. People complained the Snugpak had poor stitching and I did not want to take the chance. This MFH bag is German made and there are no issues with stitching quality. It is excellent all round, has many compartments and a multitude of ways to use (pass belt through, attach to belt, wear via shoulder strap, clip to Molle system and so on). This is an extremely well thought out product in terms of design - they really have thought of all the ways somebody may wish to use a bag like this and accounted for it. I have no hesitation on recommending this bag. You could go with a Maxpedition bag and pay a lot more, but I think you will be paying for the brand name, or you could go for the Snugpak which might let you down. I took a chance on this and couldn't be happier.
For those who are in to bushcraft or wild camping: I have an mKettle and it fits in the main compartment with Trangia and a few extras on top. End pockets are great for 2oz tins - maybe firelighting equipment. The front zipper pocuh is where I like to put First Aid kit (reachable in case I fall and land on my back while wearing backpack, have a broken arm and cannot get the backpack off to get in to it).
In the main compartment there is a mesh divider against one side and you can place an OS map here if you want. There are also plenty of ways to hook on extra things on the outside if you want.
