No two outdoor trips are the same—your gear, environment, and needs are always changing—and the Peak Design Outdoor Backpack 45L is a lightweight internally-framed backpack designed to handle it all without forcing you to make sacrifices.
From it's exquisitely comfortable harness system, to it's big, beautiful access points, to its totally customizable internal and external organization, the PD Outdoor Backpack 45L incorporates a ton of innovative features that just work, so you can spend more time enjoying the outdoors and less time wrestling with your gear. Designed to work with Peak Design's wide array of Packing Tools*, which let you dial in your protection and organization for any combination of clothes, provisions, camping gear, sport equipment, and camera gear—from a single camera/lens up to a full professional creative setup.
A uniquely versatile and low-profile harness and adjustment system gives maximum comfort to the most inclusive range of body types of any bag on the market. Vest-style straps take load off your arms and shoulders and distribute it across more of your body while also providing ideal quick-access storage and Capture Camera Clip* attachment points. A removable, stowable, hyper-adjustable padded Hip Belt provides additional support, storage and Capture Clip* attachment points. This bag is highly abrasion-resistant and functionally weatherproof thanks to it's Terra Shell 210D ripstop nylon fabric which is 100% recycled, Bluesign approved, and PFAS-free. An optional Rain Fly* provides full waterproof protection.
Other unique features include the proprietary Ultra Cinch roll-top access point for easy packing and unpacking, that allows lightning-fast 1-handed access and 10.5L of expansion. A huge rear access panel makes packing a breeze and also provides an ideal format for outdoor camera carry using Peak Design Camera Cubes* which securely clip inside the bag. 5 massive external Flex Pockets™ provide quick-access storage for large items (water bottles, hiking poles, jackets, tripods) yet always maintain a clean profile, never looking floppy or discheveled. Cord Hook™ external Carry Cords and elastic Gear Loops provide endless options for strapping things to the outside of your pack, and Cord Rails™ provide 360-degree attachment points. You can even attach Peak Design Ultralight Packing Cubes* for modular external storage. Fair Trade Certified and 100% carbon neutral.
Fits up to a Large Camera Cube. Designed for gear-heavy single-day adventures, or light overnight use. Want something smaller? Try the Outdoor Backpack 25L.
