The perfect middle ground between our 2L and 7L models, the Outdoor Sling 4L is an ultralight cross-body bag toes the line between organization and compactness. The convenient pocket layout of our 7L sling, but with a smaller footprint that's perfect for carrying 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 shoulder 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% recycled 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, an external zip pocket with a key tether, and 3 internal mesh pockets for sequestering small stuff. Fair Trade Certified and Climate Label Certified.

Eli ★★★★★

It's noticeably lighter than my old daypack, and the cross-body strap keeps it snug against my hip even on longer walks. The 4L size hits that sweet spot where I can fit a water bottle and a light layer without the bulk of a bigger bag.

Zoe ★★★★★

The pocket layout on this 4L is exactly what I needed—it keeps my phone, keys, and wallet sorted without feeling bulky. It's light enough that I forget it's on until I need something, which is rare for a sling this size.

Jacob ★★★★★

The 4L is the perfect middle ground—I can fit my wallet, keys, and a light layer without the bulk of my bigger bag. The pocket layout keeps everything organized and easy to grab on the trail. Surprisingly light on the shoulder even when it’s packed out.
