The Chest Protector 4.5 Jacki provides premium protection for the chest and back. It is constructed from a combination of hard shell and 3DF AirFit soft impact foam. Shaped specifically for the female form, the 4.5 Jacki features a 3D pre-curved design and a slightly shorter back section. Adjustable over-the-shoulder straps guarantee an excellent fit, and the ventilation slots ensure maximum airflow. The multi-plate articulating design enhances comfort by allowing natural movement. For added versatility, the front and rear plates are removable, and the BraceOn system allows for a seamless neck brace fit.
