The Dorr Slim Pack Pure Backpack is a fantastically versitile backpack, as it is very slim, but takes a huge amount of equipment. The interior is orange with moveable sperators so equipment can be packed efficiently and effectively and the transparent net prevents equipment from falling out when the bag is first opened. The whole of the interior is easily removed, to offer a huge space for clothes, or books, or anything else that needs carrying. It has an intergrated rain cover which offers added protection and the main compartment unzips at the rear of the bag, so it prevents theft. It can take a small tripod by fitting the legs of the tripod into the large side pocket and using the adjustable strap on the side of the bag to secure the top. The padded, webbed shoulder pads are incredibly comfortable and perfectly designed for long treks over the mountains. It is manufactured to a really high standard and has been well thought through. The Dorr Slim Pack Pure Backpack also has a great removeable case for iPads, or small laptops, which is secured to the opening flap.
