Our Two Cents

Introduced in 2015, as part of the new Nucleon line of chest and back protectors, these KR-Ci Chest Protector Inserts are made to fit into Alpinestars jackets and suits that have chest protector pockets for armor. These chest pads offer CE Level 1 protection. In order to receive CE Level 2 a chest protector must be a single piece.

The KR-Ci is the replacement for the Bionic chest pads. And these new chest pads are “backward compatible” with older Alpinestars jackets or suits that were advertised as being able to accept Bionic chest pads.

For reference, here are some overall dimensions of the two sizes:

XS/Small: 8.25” x 5.25”

Med/Large/XL: 10” x 6.25”
