Because the Shimoda Dslr Core Unit V3, Large is meticulously designed for photographers who demand both functionality and protection, it integrates seamlessly with the side access of Shimoda's Action X40, X50, and Explore 35 backpacks. This versatile core unit also fits perfectly in the X70 backpack, as well as the Carry-On and Dv rollers, maximizing the internal storage capacity of these bags. Featuring all the popular attributes of the Core Unit system, this large unit includes Eva laminated dividers and sidewalls, offering enhanced protection and durability. The lightweight, versatile removable skin adds an extra layer of convenience, while the internal frame provides additional rigidity and support, ensuring your gear remains secure and stable. The Dslr depth is specifically tailored for mirrorless and Dslr cameras, including gripped bodies, up to 16 cm (6.3 inches) tall, making it an excellent solution for housing multiple camera bodies and long lenses. Designed to accommodate mid- to pro-size camera equipment, such as gripped mirrorless or Dslr bodies, its generous 40 cm (15.8 inches) internal length allows for the transport of longer telephoto lenses and other items requiring extended length.For photographers who need quick access to their gear, the Large Dslr Core Unit features an integrated side access. This innovative design allows for simultaneous full rear-access and side-access, connecting seamlessly to the side-panel door of an Explore or Action X backpack. The modular stacking capability of the Large Dslr Core Unit offers even more flexibility. In larger packs like the Action X70, users can stack a Small Dslr Core Unit on top of the Large, providing additional gear capacity. The included lightweight, water-resistant skin serves a dual purpose. Primarily, it acts as a storage and dust cover for the padded Core Units, keeping your gear sealed and dust-free when not in use. Additionally, it can be used as a packing cell, allowing you to fill it with clothing or other items for efficient packing in your backpack or carry-on roller.Constructed with Eva protective shell, dividers, and frame, the walls and dividers of the Core Unit ensure superior protection compared to cheaper Pe foams commonly used in other camera bags. The Eva material allows for greater control over the density and quality, safeguarding your gear with precision. The internal frame ensures the walls remain upright, preventing collapse under weight and maintaining proper weight distribution, eliminating internal sagging. This thoughtful design allows for thinner walls, conserving internal volume while still providing exceptional protection for your valuable equipment..
