You can choose from three sizes. The larger the size, the more additional gear you can store. All three sizes also accommodate water bottles, outdoor equipment, and personal items. Designed for photographers who need a versatile backpack to protect their camera and outdoor gear, the Flipside Trek strikes the perfect balance between camera compartment and accessible storage space, equipped with all the features you expect from an outdoor backpack. 50% camera compartment, 50% accessible storage space for personal items. The body-hugging opening of the Flipside allows you to access your gear without having to set the backpack down. The ActivZone harness system provides all-day carrying comfort. Multiple attachment points allow you to increase or decrease the amount of gear secured externally. The integrated All Weather AW Cover can be unfolded from a zippered pocket on the backpack lid to provide additional protection against rain, snow, dust, and sand. The padded CradleFit pockets offer support and protection for your tablet. Stretch mesh pockets on both sides of the backpack can hold water bottles and other items.
