Peak Design Outdoor Sling shoulder bag, 4 l, Black

Peak Design Outdoor Sling Bag

An ultra-lightweight outdoor sling bag, this is the ideal mid-size option between the 2L and 7L models. It's an ultra-light sling that balances simplicity, compactness, and sufficient capacity. It offers pocket organization similar to the 7L model but in a smaller design, perfect for carrying essential gear on trips or for everyday use.



A clean design, thoughtful details, and a focus on functionality will make your life easier in every way. The quickly adjustable padded shoulder strap with a reinforced nylon buckle allows for crossbody or hip carry. Outer material: lightweight Terra Shell™ 210D ripstop (100% recycled nylon) is abrasion-resistant and of course water-resistant, as it is equipped not only with a PU coating but also with an external PFAS-free water-repellent finish. Both pockets are covered by a robust yet very lightweight 5mm waterproof UltraZip™. The Outdoor Sling features a padded back pocket with a magnetic closure for your phone, a front zip pocket for quick access, and a main compartment containing a mesh organizer with 3 smaller pockets for batteries, SD cards, keys, glasses, and other small items.



Fair Trade certified and 100% climate-neutral manufacturing.
