The perfect middle ground between our 2L and 7L models, the Outdoor Sling 4L is an ultralight cross-body bag toes the line between simplicity and capacity. The streamlined feature set of our 2L sling, but with a larger payload that handles your adventure essentials, and then some. Use the 4L Sling on it's own, or as a sidekick to one of our Outdoor Backpacks. A quick-adjusting padded shoudler strap allows comfy cross-body carry, and is easy to remove, reverse, or clip around other things thanks to it's custom glass-reinforced nylon hardware. The strap also allows for waist carry. 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 UltraZip™. There's a padded drop pocket for your phone with magnetic closure, and 2 internal mesh pockets for sequestering small stuff. Fair Trade Certified and Climate Label Certified.
