The ANNEX LAPTOP CASE is compatible with the X-PAK EVO. As the internal sleeve can only fit up to a 13", the A.L.C. will allow you to carry a larger laptop. The case can also be used independently.
When using the A.L.C. on your X-PAK EVO, we recommend purchasing the Backpack Harness Kit (sold separately) in conjunction with the A.L.C. As it can get heavy carrying it as a sling with a large laptop, the Backpack Harness Kit will provide better weight distribution and comfort.
To check to see if you have the newest X-PAK EVO, take a look at the upper hypalon webbings on both right and left sides of the bag. If you see a hole on the hypalon webbing, then you are good to go. These holes are where you will attach the buckle that comes with the A.L.C. See photo below.
