Alpinestars Bond Helmet SM5

Description

Introducing the revolutionary SM5 helmet, the culmination of over five years of rigorous research, development, and testing. We meticulously examined every detail to create a helmet that prioritizes safety and offers unparalleled comfort and protection.

This lightweight helmet boasts a thermo-injected shell made from a unique polymer blend, featuring varying thicknesses to provide the ideal balance of impact protection and minimal weight. The five-density EPS liner is strategically designed to deliver the perfect density in specific areas for superior impact absorption.

Additional standout features include a specially designed raised area with padding to effectively reduce the forces transmitted to the collarbone, and a patented visor release system that guarantees the visor detaches with the precise amount of force required, regardless of the impact angle.

Construction

The lightweight outer shell is crafted from a state-of-the-art impact-resistant thermoplastic available in two sizes.

Both the inner and outer surfaces are designed to reduce the effects of angled impacts.
A multi-density inner liner ensures the proper density is placed in the right areas for improved impact absorption.
The patented visor release system guarantees the visor detaches with the precise amount of force needed, regardless of the impact angle.
Enhanced ventilation and efficient heat transfer are achieved through multiple air inlets and exhaust ports.
The visor is designed to channel air into these ports for improved airflow.

Protection

• Stainless steel D-rings provide a secure and snug fit.
• Weighing in at just 1260 grams for a size Medium (ECE).
• The SM5 helmet meets ECE certification standards.
