Peak Design Outdoor Backpack 18L Description

A compact and lightweight frameless daypack ideal for day hikes, hydration, and commuting, the Outdoor Backpack 18L has all the comfort and versatility of our larger packs, but with a simplified design and aesthetic that feels at home on or off the trail. Designed to work seamlessly with Peak Design's wide array of Packing Tools*, which let you dial in your protection and organization for any gear—including your camera equipment.

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. Add the optional padded, quick-attaching, hyper-adjustable Hip Belt* for additional support, storage, and Capture* attachment options. 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.

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. 2 roomy external stretch pockets provide storage for oft-accessed stuff (water bottles, hiking poles, jacket, tripod, etc.) yet always maintain a clean profile, never looking floppy or disheveled. 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.

Olivia ★★★★★

I was pleasantly surprised by how much I could fit in this pack despite its small footprint, and the built-in hip fins actually kept the load stable on my last hike. The back panel has just enough padding to keep things comfortable without adding bulk.

Timothy E. ★★★★★

The magnetic buckle on the front makes it so easy to open and close one-handed, which is perfect when I'm fumbling for my water bottle mid-hike. The side pockets stretch enough to hold my phone and a granola bar, and the whole pack feels solid without weighing me down. I’ve used it for a few short h

Harper U. ★★★★★

I was worried it might be too small for a day hike, but the 18L fit my hydration bladder, a light jacket, and snacks with room to spare. The waist strap really helps distribute the weight on longer treks.
