his black m-Trekker BP150 Backpack from Lowepro is a camera bag that can comfortably hold a small DSLR along with two to four lenses, while users of mirrorless camera systems can fit up to three lenses along with a camera, plus a flash and back-up camera.

This m-Trekker BP150 can be carried by its built-in top handle, or worn using its adjustable shoulder straps which are complemented by a padded rear panel that cushions the back and shoulders, helping to ensure comfort. Before the backpack's rear panel, a top-facing zipped pocket can be dedicated for items that need to be accessed quickly and conveniently, such as a pair of sunglasses or music player earphones. Access to this m-Trekker BP150's main compartment is achieved by first placing the rear panel on a flat surface. Its front panel can then be unzipped and flipped open to reveal two memory card pockets over eight adjustable and removable dividers which can be configured according to the specific camera equipment being stored or carried.

Along the inside of the front panel, a dedicated pocket for 13" laptops or tablet computers is located behind two, zippered mesh organizer pockets. When the front panel is closed, the laptop or tablet computer pocket is positioned above the backpack's base to help minimize the effect of any bumps or shocks upon its contents.

Featuring a durable nylon construction, this m-Trekker BP150 is built to be weather-resistant and includes a seam-sealed cover for use under heavy rain. Along the outside of the front panel is an additional zippered accessory pocket, while two bottom gear straps allow for extra items such as a tripod to be clipped or tied under this backpack. Additional exterior storage capacity is provided by left and right stretchable side pockets that can each hold a water bottle, or any other similarly-sized items to be kept within easy reach.
