The CityWalker 30 Messenger Bag (Blue Slate) from Think Tank is a soft, padded multi-functional bag that holds your one standard size body with a 24-70mm f/2.8 attached with 2-4 extra lenses, flash and up to a 15" laptop held in its own padded compartment. It also accommodates a detached 70-200mm f/2.8 lens.The bag contains a removable padded insert that, when removed, transforms the bag into one large storage space-messenger style. This double-edged approach to a camera bag gives you the freedom to carry camera gear or, when the insert is removed, other items such as books or personals.The bag is accessed by a double security front snap buckle or touch fasteners that feature Think Tanks Sound Silencers to minimize the noise that traditional touch fasteners generate when opened. This will come in handy when you are shooting in quiet venues such as a chess match or courtroom. The front zippered organizer pocket hold everything from cleaning cloth to pens, note pad, lens cap and other small items. The front pocket is expandable via an easy to use touch fastener.The overall material is water-resistant and soft providing a body conforming design that makes navigating through crowds and subways much easier. A combination of nylon, polyester, polyurethane and YKK zippers provide strength to the bag. Movable closed-cell interior dividers allow you to configure the bag to suit your gear needs.The CityWalker is carried by its cushioned, adjustable, non-slip shoulder strap or convenient top grab handle. The bag comes with a seam sealed rain cover that will protect the entire bag when the weather turns against you. Topping off this bag is a business card slot located under the front flap. This will make networking easier when you need to hand your card to someone while on the go. Think Tank backs the CityWalker with a lifetime warranty against manufacturers defects. Dedicated compa
