No two outdoor trips are the same - your gear, your environment and your needs are constantly changing - and the Peak Design Outdoor Backpack 25L is a lightweight, frameless daypack that adapts to everything without you having to compromise. Innovative functions With an incredibly comfortable carrying system, spacious and practical openings and fully customisable internal and external organisation, the PD Outdoor Backpack 25L offers a range of innovative functions that simply work, so you can spend more time outdoors and less time adjusting your gear. Practical packing solution Other unique features include the original Ultra Cinch roll-top seam for easy packing and unpacking, lightning-fast one-handed access and a 5-litre expansion option. A large back panel makes packing effortless and also provides an ideal solution for transporting a camera with Peak Design's Camera Cubes (X-Small), which can be securely attached to the backpack. Spacious pockets and versatile attachment options Three spacious external flex pockets provide quick access to larger items (water bottles, trekking poles, jackets, tripods) while maintaining a compact profile. Cord Hook attachment straps and flexible gear loops offer countless ways to attach items outside the pack, while the Cord Rails provide 360-degree attachment points. Ergonomic comfort vest-style shoulder straps take the strain off your arms and shoulders by distributing weight evenly across your body, while providing convenient quick-access pockets and attachment points. Optionally, you can add the padded, quickly detachable and easily adjustable hip belt for extra support and storage space (sold separately). Durability and environmental awareness The backpack is abrasion and weather resistant thanks to the Terra Shell material, which is made of 210D ripstop nylon, 100% recycled, Bluesign certified and PFAS-free.
