Lowepro Pro Trekker 400 AW Backpack Lightweight and rugged expedition camera backpack with hydration compatibility. Purchased when my wife was into photography, used only a few times. All damage is shown in the images. No noticeable scratches or stains, and nothing that interferes with use. The rain cover's waterproof coating feels a little sticky to the touch, but it is usable. Designed to carry 1-6 professional DSLR camera bodies with grips and lenses (up to 400mm f/2.8), 4-6 additional lenses, 2 lash units, a tripod or monopod, accessories and personal gear, and a wide-screen laptop computer up to 15.4 inches. AZ Dobby ballistic nylon polyurethane with Hypalon trim, Berlex brushed nylon and polyurethane lining, and HDPE (high-density polyethylene) inner foam padding. Includes a set of padded, adjustable dividers (4 pieces) to customize the interior. The backpack lid enhances security and weather protection and can be removed to function as a waist pack with a mesh-covered back pad. It also has an All Weather AW Cover with cinch straps to protect the pack from rainwater. The front pocket has a 15.4-inch laptop sleeve that complies with most airline requirements, so you don't need to remove your laptop from the sleeve at security checkpoints. Three integrated tripod sleeves on the front and sides of the pack store and secure tripods, monopods, trekking poles, and ski poles. There are two large side pockets for storing large accessories and personal items. One is a seam-sealed pouch that can hold hydration, 4 memory card pockets, and a removable cord management pouch. The removable waist pack has two spacious pockets and a key clip. SlipLock attachment loops and sturdy D-rings are used to carry optional accessories. It has a 10-point adjustment system that can be customized to fit the upper back, shoulders, torso, chest, waist, and hip areas of the pack.
