Peak Design Outdoor Sling 4L - Kelp

The Peak Design Outdoor Sling 4L in Kelp is an ultralight cross-body bag from the Outdoor line. A quick-adjusting padded strap allows shoulder or waist carry, and the Terra Shell™ 210D ripstop shell made from 100% recycled nylon shrugs off weather and abrasion.

Designed to work on its own for fast-and-light days or as a sidekick to the Outdoor Backpacks, the Outdoor Sling 4L takes the pocket layout of the 7L model and shrinks the footprint for everyday carry and day trips.

The padded non-slip strap adjusts with one hand and is easy to remove or reverse thanks to glass-reinforced nylon hardware. The Terra Shell™ exterior has an internal PU coating rated at 1500 mm hydrostatic, a PFAS-free water-repellent finish and weatherproof #5 UltraZip™ zippers sewn with UHMWPE thread.
