The ACPRO1700 Ape Case sling pack features their signature Hi-Vis™ Yellow interior, built-in retractable water proof any weather cover, and high-styled zipper pulls and accents. The Hi-Vis™ makes seeing and finding your equipment and accessories inside your Ape Case much easier. The sling pack features a three-way access system, with top, side and back access to equipment. The top: a double-zippered top flap provides access to a large compartment for personal items such as MP3 players, phones, GPS and more. It opens away from you for easier unencumbered access without removing the pack. It also provides top access when the bag is converted to long lens bag mode. The side: a clever side panel with double-zippered flap provides quick access to your DSLR, media cards, batteries and more. Get to your camera fast without taking the backpack off. The back: the entire double-zippered back panel provides access to the entire pack’s interior for easy loading. The sling-type single shoulder strap system allows the swing pack to be swung around in front of the photographer, providing access to a camera with mounted lens, for fast shooting right out of the bag. The ACPRO1700 easily converts to a long lens bag to house large aperture telephoto lenses. The built-in and retractable side mounted tripod caddy system, along with the multiple exterior and interior pockets, and sleek trim silhouette for efficient functionality round this out as the ideal bag for any photographer.
