Bio-based Nucleon PLASMA compound
The Nucleon PLASMA Divided Chest Protector Insert is constructed from a bio-based viscoelastic impact-absorbing compound containing no less than 25% bio-based content. The PLASMA material dissipates impact energy and significantly reduces transmitted forces through controlled material response.

Low-profile PLASMA geometry
The compound is molded into a precision-engineered, low-profile PLASMA geometry developed to compress and extend with movement while supporting airflow through its channeled and highly perforated design. The ultra-adaptive, vented, low-profile Nucleon PLASMA viscoelastic compound provides superior rider comfort.

Soft tactile inner liner
The protector is constructed with a soft tactile inner liner for additional rider comfort.

Lightweight divided insert
The lightweight divided chest protector insert is available in two sizes.
