Lowepro ProTactic 350AW
Camera backpack £170, $200 www.lowepro.com
The ProTactic comes in two sizes, 35 and 45 litres. The smaller is large enough to snugly fit a Nikon D810 with 70-200mm lens attached, plus a couple of other lenses, separated by movable dividers. The main rear access has a pocket for a 13-inch laptop, and there are plenty of smaller pockets and a semi-hard shell case pocket at the top of the bag. The exterior features stitched-in straps that offer an easy way to attach tripods. One of the best-thought-out bags on the market.
