Clamshell Design The Patent-Pending clamshell design with integrated compression buckles allows you can control how the bag is opened for easy camera access. Based on your preferences, it can be used as a top-open, left-side open, or right-side open. The compression straps serve to segregate these three "zones" and protect again over-opening in any one zone. Exterior Construction The Ranger DSLR Backpack is constructed in premium, water-resistant Cordura. Genuine large gauge YKK zippers with custom metal pulls for strength and dependability. Durable non-skid bottom. Comfort The design of the straps has been thoughtfully designed to provide the most comfortable experience while carrying your camera gear on a full day excursion. The one-piece strap is designed to be ergonomic while the padding and air-mesh provide comfort and breathability. Camera Storage The Ranger Backpack features a padded and fleece-lined multi-use main compartment with configurable and removable EVA foam partitions to store all of your camera gear. Zippered mesh accessory pockets throughout the internal portion of the bag help organize smaller accessories and cables. Laptop/Tablet/Phone Storage The side entry zippered laptop sleeve will hold up to a 15" MacBook Pro. This compartment is padded soft faux-fur lined. The side of the bag has a faux-fur lined zippered phone pocket.
