The DV Core Units are specifically designed for the Action X70 Backpack and DV Roller. The Large size is designed to carry and protect all the DV gear you need. An additional 20cm depth makes it ideal for RED or similar-sized film/video cameras and DSLRs with super telephoto lenses. Like all Shimoda Core Units, it consists of high-quality EVA laminated dividers and side panels, a lightweight and versatile removable cover, and an aluminium frame that provides additional rigidity and support. The Large DV Core Unit is just enough to fully load the X70 and DV Roller, so it can be combined with a Small DSLR Core Unit for additional configuration options.
