Safety: DOT-All snowmobile helmets should at least carry the minimum of a DOT standard.

Snell--As an independent non-profit group, Snell has set a higher regulatory standard for helmets to ensure safety and durability of the product.

All modulated snowmobile helmet reviews stress the necessity of meeting a minimum of these standards.

Comfort: Internal design, weight, and comfortable fit of the helmet are of utmost importance. Snow riders emphasize seamlessly-operating buttons and clasps, sophisticated visors, advanced fog fighting systems and moisture control vents.

Features: After going through thousands of reviews, we conclude that most riders opt for the best in design and additional features. The best modular snowmobile helmet would provide comfort and safety along with aesthetic appeal and loads of features.

• Helmet size and fit: It is essential to find a helmet that fits perfectly. A larger size may come loose during the ride or slide off, thereby obstructing your view during the ride. A smaller size can be very uncomfortable. If you are purchasing the helmet on-line, you should look at the size chart before finalizing on the product.

• Material: Lightweight, polycarbonate shells are the most durable and sturdy when it comes to modular snowmobile helmets.

• Dual-pane shields: A dual-pane, anti-scratch, UV-filtering shield is an absolute must in a snowmobile helmet. They help in minimizing the fog on the shield. A layer of inert gas between the two panes provides insulation against heat transfer. Heat transfer can otherwise cause fog due to condensation.

• Framed/frameless shields: Dual-pane shields are often surrounded by a plastic frame to seal the panes. Advanced lens technology has made it possible to make frameless helmet lenses that achieve the same seal. Frameless shields are now much in vogue. But, apart from the aesthetic appeal, there is no other advantage to a frameless shield.

• Heated Electric Shield: Although dual pane shields go a long way to prevent fogging, to completely eliminate fog formation, a heated electric shield is required. The heating elements powered by the snowmobile’s electric system runs all along the outside rim of the shield, to prevent any condensation.

• Breath Guard: This feature, in addition to the dual pane, controls fogging. Ideally, a breath guard should fit snugly over your nose and face to help deflect your breath downwards. Breath guards are fixed in place either by Velcro or snaps. Integrated or removable breath boxes are the optimum choice.

• Ventilation: Ventilation in snowmobile helmet is essential to clear out the moisture build-up from the rider's breath. The optimal choice is helmets that have adjustable vents.

• Single button operation: A responsive button for flipping the chin bar or releasing the face shield with one hand is a desirable feature in a modular snowmobile helmet.

• Visors: Built-in sun visors that can be flipped up or down according to the rider’s convenience are an added advantage.

• Speaker cavity: Built-in Bluetooth-enabled speakers cavities are a new fad and are increasingly in demand.

• Safety Rating: The safety rating of a snowmobile helmet is very important. DOT, SNELL, and ECE are all separate safety rating systems that grade helmets according to their shock absorbing capacity, ability to withstand a blow from a sharp object, the ability of the chin straps to stay fastened, and peripheral vision.
