6D - Alterra Segment Helmet (MTB)

For long pedals and big descents, the 6D - Alterra Segment Helmet (MTB) is easy to live with: quiet on the climb, planted when the trail turns rough, and confidence you can feel when speeds pick up. 6D’s ODS® system floats the inner liner to help manage both sharp hits and twisting forces, so crashes feel a little less chaotic and rides feel a lot more relaxed.

Out on the dirt, Emergency‑release cheek pads add a layer of peace of mind, an adjustable visor dials in coverage and goggle parking, and multiple shell/EPS sizes help nail the fit. It’s the kind of helmet that disappears on the climb and shows up when it counts.

Features:

• ODS® (Omni‑Directional Suspension) reduces angular and linear impact energy.
• Dual‑layer liner system with multi‑density EPS/EPP and isolation dampers.
• Active ventilation with multiple intake and exhaust ports for airflow.
• Comfort liner is removable, washable, and anti‑microbial.
• Emergency‑release cheek pads for safer helmet removal.
• Clavicle‑friendly shell cut‑away reduces collarbone contact.
• Compatible with most popular neck‑brace systems.
• Secure D‑ring closure for a reliable fit.
• Optimized fit with multiple shell and EPS sizes (model‑dependent).
• Adjustable visor with lightweight alloy hardware (where applicable).
• Protective helmet bag/case included (model‑dependent).
