Alpinestars Nucleon KR-Cell CiR Chest Protector

Experience the pinnacle of track-focused safety with the Alpinestars Nucleon KR-Cell CiR Chest Protector. Engineered for the uncompromising demands of the circuit, the NUCLEON KR-CiR is a high performance, lightweight track and race chest protector designed to offer elite-level impact absorption without hindering rider mobility or comfort. This essential piece of rider protection is meticulously crafted to integrate seamlessly into a rider´s gear, providing confidence and security when pushing the limits.

The Nucleon KR-Cell CiR is built around an innovative micro-structure technology that is both incredibly strong and exceptionally light. This advanced design not only dissipates impact energy with remarkable efficiency but also provides outstanding flexibility, allowing the protector to conform perfectly to the rider´s body. The ergonomic, pre-contoured race fit ensures that it remains securely in place under a leather suit, moving with you as one and eliminating distractions, so your focus remains solely on the ride.

Ventilation is paramount for maintaining performance during intense track sessions. The KR-Cell CiR addresses this with a highly perforated structure, featuring extensive air channeling on its interior. This design promotes maximum airflow, drawing heat and moisture away from the body to keep you cool, dry, and comfortable, lap after lap. The soft, comfortable lining further enhances the rider experience, providing a pleasant feel against the body or base layer.

For riders seeking a complete, top-tier protection system, this chest protector is the perfect counterpart to Alpinestars´ back protection range.

Ricardo Oliveira

I needed this protection for my suit, alpinestars too. Until you see I haven't tested it on asphalt and I'm going to try not to! But it's very comfortable to wear, premium material that appears to have a long lifespan. For the cost there is no need to invent, it is to buy.
