CIRAS is a modular protective vest designed for US Special Operations Forces by Eagle Industries. The vest is currently the new FSBE II system and has replaced the FSBE AAVs. It features PALS webbing, making it MOLLE-compatible and allowing the attachment of various pouches or accessories. Two versions of the vest are available, known as the "land" and "maritime" versions. The vest consists of front and rear panels with pockets for BALCS or SPEAR-cut soft armor panels and standard-issue SAPI plates. This gives the wearer up to NIJ Level IV protection on the front and back and Level IIIA protection on the sides. On the lower rear side of the front of the vest, there are two quick-releasable buckles for attaching groin protection. The wearer's sides are covered by an external cummerbund, which is also covered with PALS webbing. The vest body is constructed of 1000-denier Cordura Nylon, and the interior is lined with heavy-duty mesh to aid in cooling the wearer.
