I have travelled across the globe with this bag and it's a comfy bag with padded waist and shoulder straps...just not so good for daily use of quick access when you need to change your lens.....but a great price.....
here is the guff.....
"Side Entry Compartment provides easy access to D-SLR equipment and accessories, even when pack is being worn"
"Triple Compartment Design ensures superior camera protection, notebook protection (fits up to a 17"" Widescreen), and organizes personal accessories"
180-Degree access panel with adjustable dividers provides excellent protection in a customized fit that's easy to load.
"Outer accessory pockets provide external storage for other accessories with fast access, including a harness pocket for an MP3 player or Mobile Phone, as well as a Mesh side pocket for a water bottle or other personal items."
"Tough, water-resistant outer fabric protects against moisture and abrasion"
