The Lowepro Flipside 400 AW II Backpack is a high-capacity, dynamic storage system that's able to be configured to accommodate a wide variety of camera equipment. It has "flipside" access where you can safely keep your gear accessible only from the back and away from passersby. The padded waist belt makes the load more comfortable while a rain cover keeps everything dry. It has a laptop pouch, a tripod cradle, and a mini-bag for accessories, as well as removable dividers. It also has mesh side pockets for water bottles and more. This bag will fit a lens up to 300mm, or a combination of 4-5 mid-range zoom lenses with a DSLR. It is not quite small enough to comfortably fit under the seat of a plane but should fit nicely in overhead storage. This durable bag is a great option for travel or on-the-go gigs.
