The official 6D ATR-3 Comfort Liner is the genuine OEM replacement comfort liner for the 6D ATR-3 adult motocross helmet. Replacing your comfort liner restores hygiene, fit accuracy, and helmet performance without the cost of a full replacement.
Made with Dri-Lex® antibacterial fabric — the same premium material used in the original helmet — this liner wicks moisture away from the head during riding, regulates temperature, and resists bacterial growth. Fully removable and machine washable. Ensure your helmet maintains its certified comfort and fit profile by using genuine 6D replacement parts only.
Compatibility: 6D ATR-3 adult motocross helmets. Select your helmet size when ordering.

6D Helmets is an American premium helmet manufacturer specialising in Omni-Directional Suspension (ODS) technology for motocross and off-road applications. The ODS system uses dual-foam construction with elastomeric isolation dampers positioned between the inner and outer helmet shells, designed to manage both linear and rotational impact energy in a single integrated structure.
The ATR-2 and ATR-2Y models are produced in composite fibreglass and full carbon fibre shell configurations, certified to ECE 22.06 standard. 6D helmets are built for riders who prioritise impact energy management over minimum certification compliance — ODS technology reduces peak G-force transmission at impact velocities where single-foam helmets reach their energy absorption limit. Available in full-face motocross configuration with separate visor adjustment.
