Minimalist, comfortable and functional, the Iterus 38L is the lightweight backpacker’s dream pack.

Suitable for multi-days trips for ultralight adventurers with low base pack weight and volume, and perfect for weekend trips for more traditional hikers.

The Iterus 38L is a frameless pack that features some of the most technologically advanced waterproof materials to create a pack that is both very lightweight and durable.

• Convenient roll-top closure
• Functional 4-point compression cords that fully cover the pack sides from top to bottom, allowing to significantly reduce pack volume when needed.
Big stretchy spandex/nylon front mesh stores a lot of gear.
