Design Concept & Background
""
Built for aggressive dirt performance, the 6D Helmets 6D ATR-2 is crafted for intense dirt riding with ultra-wide goggle eyeport stabilization across punishing tracks and trails. Its Advanced Multi-Composite (Carbon-Aramid-Glass / AIM+) shell tips the scales at 1422g, channeling boundary-layer airflow to maintain a ~99 dB acoustic cabin profile while meeting DOT, ECE 22.05 impact standards. An ultra-breathable, antimicrobial interior liner stabilizes the helmet during aggressive terrain vibration, locked in securely with track-proven Double D-Ring retention.
