Nature, wildlife and adventure photographers packing a Pro DSLR with an attached lens, three extra lenses, a flash, a GoPro, accessories, and personal items for their next expedition will appreciate the gray Whistler BP 450 AW from Lowepro. The BP 450 AW features a zippered rear compartment with a removable insert and touch-fastening dividers for organizing your gear. The gray-colored interior facilitates locating your gear in low light. The rear lid covering the insert has a hinged back panel for grabbing a camera without having to unzip the whole lid. On the inside of the panel is a zippered accessory pocket and slip-in memory card pockets. This versatile, all-season backpack features a top pocket with a clear-mesh accessory pocket and key leash under the lid, rear gear access, and a zippered front compartment for storing personal items such as food and clothing. While navigating technical terrain wearers will value the comfort and stability of the padded, adjustable shoulder harness, chest connector, and waist belt with quick release buckle. For improved airflow and cushioning, the pack has a rear panel fabricated from heat-embossed nylon and spandex-blended fabric. Exterior attachment points and compression straps provide multiple ways to secure a tripod, hiking poles, skis, and other items. The top of the pack has a haul strap for hanging the pack on a hook and lifting or lowering it while climbing with a carabiner. When not needed as a photography backpack, one may remove the insert for conversion to a day pack. Should a weather front move in, simply deploy the included all-weather cover. Constructed of 420D and 210D nylon, the BP 450 AW is both durable and strong.
