FAQs

How much gear can the Outdoor Backpack Zip 18L carry?

With an 18L internal volume, this backpack offers enough space for day trip essentials like snacks, extra clothing, camera gear, or a hydration bladder. It’s best suited for single-day outings or minimalist setups. It also fits one Smedium-sized Peak Design Camera Cube, making it practical for photographers looking to travel light without sacrificing access or protection.

Does the Outdoor Backpack Zip 18L support hydration bladders and/or laptops?

Yes, the internal hydration sleeve is equipped with a bladder loop and can double as a laptop sleeve for devices up to 16 inches, including the MacBook Pro. While there’s no dedicated pass-through for hydration tubes, users can route the tube through the main zip area. This dual-purpose sleeve makes the pack adaptable for hiking or urban environments.

How weather-resistant is the Outdoor Backpack Zip 18L?

The exterior is made from Terra Shell™ 210D ripstop nylon with a PFAS-free water repellent coating and an internal PU layer. Combined with weatherproof UltraZip™ closures, the backpack is highly resistant to rain and abrasion. For full waterproof protection in severe conditions, a dedicated Rain Fly is available separately.

What sets the 18L version apart from the 25L model?

The 18L version is smaller and lighter, with a cleaner silhouette and simplified design. Unlike the 25L model, it lacks roll-top expansion and uses rear-only access. It also replaces the Flex Pockets with two separate stretch pockets and doesn’t include a dedicated hydration port. These changes make the 18L better suited for lighter, faster missions where simplicity and weight savings matter.
