Extraordinarily lightweight for a pack of its size and capacity — weighs less than 3 pounds. Exclusive, Switchback™ equipment module can be reversed to be accessible only from back side of the pack, for extra security. Weather-sealed YKK® zippers on all critical exterior openings keep the elements out. Water-repellant, dobby/diamond ripstop nylon shell—an optimum combination of light weight and durability. Exclusive WeatherWrap™ cover included—the fastest, easiest auxiliary rain cover around. With Switchback module reversed, equipment can only be accessed through secure hatch on the body side of the pack. Remove the Switchback module to convert from photo use to travel daypack. Large mesh side pockets for water bottle or temporary lens storage while shooting. Front accessory compartment with pockets for storage drive, phone, audio device or other small items. Huge, laminated mesh pockets hold cables, color cards, small reflectors and more. Padded, ventilated mesh back panel and harness wick away moisture.
