6D Alterra MTB Helmet Advanced Protection Meets All-Day Comfort The 6D Alterra redefines what a full-face enduro helmet can be—delivering industry-leading impact protection, a featherlight design, and premium ventilation without sacrificing coverage. Engineered with 6D's exclusive Omni-Directional Suspension™ (ODS) technology, the Alterra is built to keep you safe whether you're charging steep descents, tackling technical terrain, or spinning out long e-bike miles. At just 710 grams (M/L), it's one of the lightest full-face MTB helmets certified for DH, BMX, and e-bike standards, offering elite-level safety with day-long comfort.
