If you need to configure the upper compartment of your Rotation 180° 38L Professional Backpack for additional camera gear or other sensitive components, the Mindshift Gear Rotation 180° Pro Padded Insert is essential. The dividers in the Insert can be fully configured to fit a range of gear including a 300mm f/2.8 lens in addition to a pro body with a 70-200mm f/2.8 attached. Since it can be easily loaded into the upper compartment through the pack's back panel opening, load it either inside or out of the pack. Gear can then be accessed through the back panel or through the top opening of the pack. Compatible with Mindshift Gear Rotation 180° 38L Professional Backpack.
