Setup and Initial Use

Adjusting Capacity (26L to 45L)

The backpack's capacity can be adjusted to accommodate different loads. This feature is ideal for switching between daily use and extended travel.

• To expand: Locate the zipper running along the perimeter of the main compartment. Unzip it completely to extend the backpack's depth. Release any side compression buckles if they are fastened.
• To compact: Zip up the expansion zipper. Fasten any side compression buckles to reduce the backpack's depth and secure its contents.

Adjusting Shoulder Straps and Chest Buckle

For optimal comfort and weight distribution, adjust the shoulder straps and utilize the chest buckle.

• Place the backpack on your back. Pull the strap ends to tighten the shoulder straps until the backpack sits comfortably and securely on your shoulders.
• Fasten the chest buckle across your chest and adjust its position and tension to help balance the weight and prevent shoulder strap slippage.
