Peak Design Outdoor 18L Backpack Zip - Eclipse

Description

Compact lightweight pack for everyday outdoor and photo carry.
The Outdoor Backpack 18L distills the comfort, versatility, and modularity of Peak Design’s larger outdoor packs into a compact, lightweight daypack that feels equally at home on the trail, on the bike, or on your daily commute. Designed to work seamlessly with Peak Design’s Packing Tools ecosystem, it can be configured to carry everyday essentials, hydration, and layers—or dialed in for camera carry with a securely clipped-in Camera Cube when photography is part of the plan.

A low-profile, hyper-adjustable harness provides exceptional comfort without bulk. Vest-style shoulder straps distribute weight across your torso to reduce fatigue while offering quick-access storage and Capture Camera Clip attachment points. For heavier or longer carries, an optional padded hip belt adds stability, storage, and additional Capture mounting options.

Access and organization stay simple and intuitive. A full rear access panel makes packing easy and creates an ideal layout for outdoor camera carry, while two external stretch pockets securely hold items like water bottles, jackets, trekking poles, or a tripod without compromising the bag’s clean silhouette. Built from abrasion-resistant, weatherproof Terra Shell fabric with integrated external carry systems, the Outdoor Backpack 18L delivers adaptable performance in a refined, minimalist package—ready for whatever your day calls for, camera or not.

Fits 1 Smedium Camera Cube. Designed for light single-day adventures. Want something bigger? Try the Outdoor Backpack 25L or 45L.
