- (FIREFIRST x RADIO EVA) Capsule collaboration between Arkness Japan and RADIO EVA.
- It is a characteristic backpack that expands the storage part in a roll type. It is excellent at avoiding flooding and has an attractive design with a sporty hair shape. The EVA letters that are transparent from the mesh have a stylish finish.
- The font used in the past has been updated to Evangelion specifications and rebuilt, and durable CORDURA nylon is used as the material.
- The inside of the main room is made of highly waterproof fabric. The front has a zipper pocket for easy access to frequently used items, and the back has a zipper pocket suitable for storing valuables.
- The shoulder straps are equipped with D-rings for attaching small items and a chest belt to prevent slippage, so the practicality is not lacking.
