Sleek, ultralight, and ultra-versatile, the Peak Design Outdoor Sling 4L is an adventure companion that you can put to work during a backcountry trek or a city commute—wherever you take it, it has the clean form and brilliant functionality that feels right for the job. A quick-adjusting padded shoulder strap with custom glass-reinforced nylon hardware allows cross-body carry or waist carry, and the include Cord Hook™ Stabilizer Cord pops on to enable use during cycling and active movement. The lightweight Terra Shell™ 210D ripstop 100% recyced nylon exterior is abrasion resistant and weatherproof thanks to a PU-coating, PFAS-free water resistance treatment, and burly #5 weatherproof UltraZips™. There's a padded drop pocket for your phone with magnetic closure, an external quick-access zip pocket, and 8 smaller mesh internal pockets for batteries, SD cards, keys, glasses, and other small stuff. Carry things like an umbrella, jacket, or travel tripod externally using 2 elastic Cord Hook™ Gear Loops. Those Gear Loops can also be used to compress the bag so that it retains it's clean profile with smaller payloads. Fair Trade Certified and 100% carbon neutral.
