Built for Big Gear and Bigger Adventures
The Shimoda Mirrorless XL50 RST Action Core Unit is your ultimate solution for carrying professional camera gear into the wildest environments. Created to fill the entire main compartment of the Action X50 backpack, this Core Unit unlocks the pack’s full potential—letting you carry long super-telephoto lenses like a 600mm f/4 while still attached to your camera. Whether you're tracking wildlife across rugged terrain or capturing fast-action moments, this insert gives your gear the protection and access it deserves.
Rear, Side, and Top Access for Unmatched Versatility
What makes the RST Core Unit stand out? It’s all in the name—Rear, Side, Top. Three access points mean you’re never more than a zip away from your most important tools. Pull your camera from the side without setting your bag down. Open the rear for full access to your entire kit. Or grab your mounted superzoom straight from the top, thanks to seamless compatibility with the Action X50’s roll-top design.
Optimized for Gripped Bodies and Superzooms
Built with extra depth to comfortably house gripped mirrorless or DSLR bodies up to 6.1 inches (15.5 cm) tall, the XL50 makes efficient use of space by allowing larger lenses to stand vertically. That means faster setup times, smarter packing, and peace of mind knowing that your most sensitive gear is securely stored with minimal wasted space.
Protection You Can Count On
The XL50 uses high-density EVA foam for both its outer shell and internal dividers—offering premium protection with a slimmer profile. Unlike conventional PE foam, EVA provides more structure and resilience, so your gear stays safer with less bulk.
Skin Included for Storage and Travel
Each XL50 Core Unit comes with a lightweight, water-resistant Skin that acts as a storage case when your gear is not in use. It's also ideal as a packing cell—fill it with clothes or accessories and tuck it into your roller or backpack when you're on the move.
