The Code of Bell Backpack Harness Kit is designed to be used with the X-PAK EVO and APEX LINER PRO, transforming them into a backpack. The front chest pocket is perfect for keeping cards, earphones/earbuds, and other small everyday carry items for convenient access. It also features a waist strap for added stability.

In addition, the Annex Laptop Case (sold separately and specifically compatible with the X-PAK EVO) can be paired with the Backpack Harness to accommodate up to a 16" MacBook Pro laptop.

To determine if your X-PAK EVO is the latest version, inspect the upper hypalon webbing on both the left and right sides of the bag. If you notice a hole in the webbing, your X-PAK is compatible with the Backpack Harness.
