## Overview
- **Product**: Atlas 4.0 Track Hi-Viz Yellow
- **Brand**: N/A
- **Category**: Helmet
- **Summary**: Streckenorientierter Carbonhelm mit aerodynamischem Spoiler und Notfall-Entriegelungssystem. Der Atlas 4.0 Track Hi-Viz Yellow ist von Ruroc als hochintegres Helm-Schutzsystem konstruiert und nutzt eine Strukturschale aus Kohlefaser-Verbundschale (Carbon). Dieser Schichtaufbau ermöglicht eine progressive Dissipation kinetischer Aufprallenergie bei Stoßverzögerungen, verteilt lokale Belastungsspitzen gleichmäßig über die äußeren Lamellenschichten und minimiert die Verformungsübertragung in den mehrteiligen EPS-Dämpfungskern.
