Peak Design Outdoor Backpack 45L Kelp

No two adventures are the same—and the Outdoor Backpack 45L is built to adapt to all of them. This lightweight, internally framed pack seamlessly transitions between outdoor gear hauler and high-performance camera bag, without forcing you to choose one identity over the other. Built around Peak Design’s modular Packing Tools ecosystem, it lets you configure protection and organization for anything from clothing, food, and camping gear to a single camera or a full professional photo or video kit—or no camera at all.

A uniquely low-profile, hyper-adjustable harness delivers exceptional comfort across an unusually wide range of body types. Vest-style shoulder straps distribute load across your torso to reduce fatigue, while offering quick-access storage and Capture Camera Clip attachment points. A removable, stowable padded hip belt adds support, storage, and additional Capture mounting options when loads get heavier.

Packing and access are fast, intuitive, and frustration-free. The Ultra Cinch roll-top provides lightning-fast one-handed access and up to 10.5L of expansion, while a massive rear access panel makes loading easy and creates an ideal layout for securely clipped-in Camera Cubes. Five oversized external Flex Pockets™ swallow bulky items like water bottles, jackets, tripods, or trekking poles while maintaining a clean, streamlined profile. Built from abrasion-resistant, weatherproof Terra Shell fabric and finished with integrated external carry systems, the Outdoor Backpack 45L is designed to disappear on your back—and adapt instantly when your plans change.

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 or 18L.

Your Adventure Camera Bag

Purpose Built For Capture

Attach a Capture Camera Clip and rigidly carry your camera outside your bag, so you never miss a shot. Peak Design Outdoor Backpacks were designed with Capture in mind—dedicated padded/reinforced attachment points create the most secure, comfy camera carry experience of any backpack, ever.
