Peak Design Outdoor Backpack, 18 l, eclipse

Peak Design Outdoor Backpack

A compact and lightweight backpack, ideal for day trips or commutes. The Outdoor Backpack 18L offers all the comfort and versatility of larger Peak Design backpacks, but in a streamlined design that works as well in the outdoors as it does in the city. It's designed to work seamlessly with a wide range of Peak Design organizers*, offering perfect organization and protection for your gear – including your camera.

The running vest-style straps distribute weight effectively across your shoulders and torso, while providing ideal storage with two stretchy mesh pockets. Perfect for quick access to your phone or for carrying a soft flask. You'll also find attachment points for the Capture Camera Clip* on both straps.
This backpack is highly abrasion-resistant and functionally waterproof thanks to its Terra Shell™ 210D ripstop nylon, which is 100% recycled, Bluesign certified, PFAS-free treated, and features an internal PU coating. An optional Rain Fly* provides full waterproof protection.
The large back access panel makes packing easy and is perfectly sized for carrying photo and video gear in combination with Peak Design Camera Cubes*, which can be securely attached inside the backpack. Three large external Flex Pockets™ provide easy access to larger items you want to keep handy (water bottles, trekking poles, jackets, tripods), while always maintaining a clean look and avoiding a disorganized appearance. External Cord Hook™ straps and elastic Gear Loops offer endless possibilities for attaching items to the outside of the backpack, while the ubiquitous Cord Rails™ provide attachment points on all sides of the backpack. You can even attach Peak Design Ultralight Packing Cubes* for modular external storage. The backpack is Fair Trade certified and carbon neutral. It can hold 1 Smedium (or Small) Camera Cube.
