Designed to take a beating, the Razer Tactical Backpack is made from the same materials used for military flak jackets – thick, tightly woven robust ballistic nylon for a water-resistant, scratch and tear-proof exterior. Designed to carry laptops up to 17.3 inches, it includes an additional MicroFiber lined pouch for a tablet. The frameless design features heavily padded shoulder straps and a moisture wicking back panel for user comfort. An adjustable chest strap evenly distributes the weight of a heavier load over the back for less fatigue. The design also incorporates a rain poncho large enough to cover the entire bag, protecting it from the elements. It is backed by a lifetime warranty.
