Alpinestars Nucleon Flex Pro Protection Vest Transparent Smoke Red Black 009

The Alpinestars Nucleon Flex Pro Protection Vest is an ultra-lightweight, high-performance protective vest engineered to deliver uncompromising Level 2 protection while maintaining exceptional comfort and freedom of movement.

Its advanced hybrid construction combines Nucleon Cell and Nucleon Flex technologies to efficiently disperse impact energy while remaining highly flexible and breathable. The full-length back protector features an ergonomically contoured dual-zone design that provides robust protection without restricting mobility.

An additional Nucleon Flex layer reinforces the central back zone, enhancing protection in critical impact areas while preserving natural body movement. This intelligent construction achieves an optimal balance between protection, flexibility, and airflow.

The split Nucleon Flex Pro chest protector is manufactured from an advanced polymer blend, offering excellent energy absorption with outstanding weight-saving properties. Its microstructure is specifically designed to maximize airflow and breathability.

A soft-touch, perforated mesh chassis securely holds the chest and back protectors in place while delivering continuous ventilation for superior riding comfort.

An adjustable elastic waist belt ensures a stable and secure fit, and the vest has been extensively tested and certified to perform reliably in extreme temperature conditions.
