After looking around all the shops and comparing prices and trying to find a new bag I came across a good quality bag at a reasonable price.
The bag I bought was the Naneu Pro Uban Gear U120 Backpack which cost $147.
This is a large backpack with enough storage to hold up to a 300 f/2.8 lens with the body attached, or 2 bodies a couple of lenses and a flash (Depending on your configuration via the interchangeable padded dividers). It also has a rear compartment which can accommodate a 15.4" screen laptop. There is also 2 front storage compartments, a water bottle holder, tripod holder, padded waste strap and a headphone grommet (For your mp3 players etc). Also the camera storage compartment also has a padded divider which is designed to keep your gear safe from dust and damage (So when you open the bag your gear won’t fall out!) and you get a storage compartment inside (For memory cards, etc). And it has a nice heavy duty rubber carry handle on the top.
The bag is well built using water resistant 1680D ballistic nylon and quality stitching. There is also a life time warranty on the workmanship and defects on the bag! The bags are designed in the US.
The bag feel very solid and is comfortable to wear, My only complaint is its huge (Compared to my old backpack) and will take some time to get use to. Cheesy
This type of bag easily compares to the “Brand name” bags such as Lowepro or Tamrac bags (Which cost $300+). So if your looking for a large bag capable of carrying allot of gear and your laptop this one would be worth a look!
