Alpinestars Nucleon Plasma Racing Chest Protector

Built for performance road riding and racing in Alpinestars racing suits, the Nucleon Plasma Full Chest Protector Insert combines chest impact protection with adaptive, ventilated Nucleon PLASMA construction to support comfort and freedom of movement during intense riding.

Specifically engineered for use with all Alpinestars racing suits.
Innovative Construction: The Level 2 CE-certified chest protector insert features a composite construction and has a central semi-rigid thermoplastic zone on a Nucleon PLASMA chest protector for greater impact force dispersion in critical areas.
Advanced Impact Protection: Nucleon PLASMA is engineered with a viscoelastic material that absorbs and dissipates impact forces while remaining flexible.
PLASMA M Airflow Design: The innovative PLASMA M design delivers maximum airflow and efficient heat dissipation.
Soft tactile Backing: Soft-touch backing prevents tearing and maintains the structural integrity of the protector.
Fully Adaptive Fit: Fully adaptive design maximizes comfort during use.
Extended Rib Coverage: Extended side wings provide greater coverage and added rib protection.
Secure Jacket Attachment: Large central hook and loop panel ensures secure attachment to Alpinestars jackets, even when the jacket is open.
Anti-Slip Silicone Ribbing: Inner silicone ribbing prevents slipping and keeps the protector securely in place.

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

Adaptive, ventilated PLASMA geometry
The ultra-adaptive, vented, low-profile Nucleon PLASMA viscoelastic compound provides superior rider comfort, with geometry specifically developed to compress and extend with movement while supporting airflow through its channeled and highly perforated design.

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

Lightweight full chest protector insert
The lightweight full chest protector insert is available in three sizes to fit a wide range of body sizes.
