Due to the shipping bulk created by the curved frame and hipbelt, the Aerus 55L backpack may be delivered unassembled.

Assembly Instructions for the Aerus 55L Backpack

1- Insert the Aluminum Bars: Starting from the channel opening at the base of the pack, insert the bars with the curvature facing the back panel.
2- Position the Carbon Crossbars: Ensure the top two carbon crossbars are positioned above the aluminum bars. To insert the aluminum bars into the top reinforcement pocket, use your fingers to squeeze the pocket entrance and enlarge the opening. Extra pressure may be needed for new packs.
3- Secure the Velcro Band: Thread the Velcro band on each side of the frame through the aluminum loop located on the back side of the hip belt, and pull it tightly to create tension in the back mesh panel and enhance the frame’s arch.
4- Attach the Mesh Panel Toggles: Use your hand and slightly press down on the mesh panel with your body weight, then insert the toggles into the grosgrain loops on both sides.
5- Ready to Use: Your Aerus backpack is now fully assembled and ready for use!
