Alpinestars · Protection · Adventure / Street
The Alpinestars Nucleon Plasma Full Back Protector Insert is a lightweight back protector insert designed for Adventure and Street riding. It uses Alpinestars’ Nucleon Plasma Technology, built around an eco-friendly, sustainable impact-absorbing material that blends bio-based materials with high performance polyurethane.
For day-to-day comfort on the bike, the protector is highly ventilated and shaped to move with the rider. A soft-touch textile coating and inner liner sit against the body, while an extensive network of ventilation channels helps manage heat during longer rides or warmer conditions.
Comfort
This insert is built with Alpinestars’ eco-friendly, sustainable impact-absorbing material: a blend of bio-based materials and high performance polyurethane. The Plasma design is made to be ultra-adaptive, balancing flexibility and comfort while helping disperse force across the protector’s structure.
Ventilation
For Adventure and Street use where airflow matters, the protector is highly ventilated and uses an extensive number of ventilation channels for effective heat dissipation. On the skin side, a soft touch inner liner and a soft-touch textile coating are used to improve comfort during extended wear.
Fitment
To help riders dial in fit and coverage, the Nucleon Plasma Full Back Protector Insert is developed in 3 waist-to-shoulder dimensions. This sizing approach is intended to cover a wide range of body sizes while maintaining full-back coverage suited to its insert-style design.
