Overview
RST series Core Units allow creators to carry and access the maximum amount of gear on demanding terrain, while still maintaining Shimoda's signature comfort and reliability. RST is acronym for the Core Unit’s Rear, Side and Top access points. With the RST50 (DSLR - XL50) Core Unit, you can use the Rear access to get to all your gear, the Side for quick access to your camera without putting your pack down, or the Top to access longer mounted superzoom lens without opening the rear door.
The RST50 was specially designed to fill the entire main compartment of the Action X50 backpack, which allows the pack to fit and protect lenses as long as 20.9 inches (53 cm), such as the Sony/Canon/Nikon 600mm 4.0 (attached to camera), as well as the Sony 200-600mm and 400-800mm, Nikon 180-600mm, Canon 200-800mm, Fuji 150-600mm, and OM 150-600mm. Fits these superzoom lenses even when attached to a camera body. NOTE: RST Core Units are not compatible with Shimoda Explore series backpacks.
We call them Core Units simply because they’re the Core of the Shimoda system. Their modular versatility lets users customize their gear carrying needs with different sized camera inserts for different days, and to get more out of their backpack. While the RST50 carries the maximum amount of gear an X50 can handle, having the ability to swap out the Core Unit for smaller ones gives you the flexibility to use the best Core Unit size for the adventure ahead.
