The Ski-Doo New OEM Heated Oxygen Helmet is a solid pick for snowmobile riders looking for a lightweight, DOT-certified helmet that balances safety and comfort. Made from M-FORGE Composite material, it’s about 20% lighter than some other Ski-Doo helmets, which helps reduce neck fatigue during long rides. The helmet comes in two shell sizes, which is great for getting a better fit, and it’s designed to be comfortable even for those wearing prescription glasses. It features a ratcheting quick-release chin strap and a micrometric strap for secure, easy adjustments.

Ventilation is well thought out with precision airflow settings and a redesigned chin curtain to cut down drafts, which is important when riding in cold weather. The helmet also includes a noise control system with custom-fit ear pads, helping to keep wind and engine noise to a minimum, making rides more enjoyable. One standout feature is the heated visor controlled via a unique remote with heat indicators, which can be operated with gloves on—very handy in freezing temperatures to prevent fogging and maintain clear vision. Additionally, the helmet supports communication systems, adding to its versatility for group rides or safety.

While the helmet weighs 5 pounds, making it lightweight for a composite helmet, some users might find it slightly heavy compared to non-modular helmets. It is designed with an aerodynamic shape but does not have modular flip-up capabilities, so it is not fully modular in the traditional sense that some riders might expect. This helmet is well suited for snowmobile riders who prioritize safety, comfort, and advanced features like visor heating and noise control, especially in cold, windy conditions, although it may not meet the needs of those wanting a true modular flip-up design.
