FAQs

How large is the Outdoor Sling 4L?

The Outdoor Sling 4L measures 31.0cm in length, 17.5cm in width, and 5.0cm in height. This makes it compact enough for daily use yet spacious enough to carry more than just your bare essentials. It’s a noticeable step up from the 2L version while still being minimal in design. Whether you're carrying snacks, an extra layer, or your phone and wallet, the size is practical without being bulky.

Can the strap be removed or reversed?

Yes, the strap is fully removable and reversible, giving you plenty of flexibility in how you wear it. The Cord Hook Cam Lock hardware allows you to detach or flip the strap quickly, making it easy to switch between cross-body and waist carry. The glass-reinforced nylon hardware is strong and lightweight, and the buckle can be operated one-handed. This makes it suitable for on-the-go adjustments or attaching it to another bag or structure.

Is the Outdoor Sling 4L waterproof?

While not submersible, the Outdoor Sling 4L is functionally weatherproof. It uses a PU-coated Terra Shell nylon exterior treated with PFAS-free water repellent for reliable resistance to rain and splashes. The main zip is a durable weatherproof UltraZip™ designed to withstand grit and moisture. For everyday use in variable conditions, this construction keeps your contents safe and dry.

What’s the difference between this and the 2L or 7L models?

The 4L version includes the same features as the 2L model but with a larger internal capacity, making it better suited for longer outings or those who need a bit more space. Compared to the 7L, the 4L is more compact and does not include extra pockets or camera-carrying capability.
