Peak Design Outdoor 4L Sling

Peak Design's Outdoor Sling 4L splits the difference between the brand's 2L and 7L slings, trading a little capacity for a genuinely compact footprint without giving up the organisation. It works as a standalone cross-body bag or as a sidekick to one of Peak Design's Outdoor Backpacks. A quick-adjusting padded shoulder strap carries cross-body or around the waist, and is easy to remove, reverse or clip elsewhere thanks to its glass-reinforced nylon hardware. Inside, a padded phone pocket with a magnetic closure sits alongside an external zip pocket with a built-in key tether and three internal mesh pockets for the small stuff. The lightweight, weatherproof Terra Shell 210D ripstop exterior handles the trail and the daily commute equally well.
