(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.
