ILM 726X Matte Black Open Face Helmet (XL)
The Extra-Large ILM 726X preserves the same core protection features, offering a roomier interior for riders with broader head shapes or those who prefer slightly more space inside the helmet. Like the other sizes, it adheres to FMVSS-218 and DOT standards for reliable head protection on dirt bikes, ATVs, mopeds, and other off-road platforms. The detachable lens, sun shield, and chin guard remain essential for adapting to changing light and weather conditions. Replacement parts are designed to be user-friendly, and the ventilation system helps maintain comfort on long, hot rides. The XL option ensures a comfortable fit without compromising safety or features.
Riders who value a consistent ILM open-face experience across sizes will benefit from the XL variant due to its proportionate interior and exterior balance. This makes it suitable for a range of riding styles, from casual dirt tracks to more aggressive motocross sessions, while maintaining a sleek, matte aesthetic that complements most gear ensembles.

Its ABS shell with reinforced composite delivers sturdy protection, while the cushioned lining enhances comfort for long rides. Weighing around 900 grams, this helmet offers a comfortable, lightweight fit that doesn’t sacrifice safety. The quick-buckle chin strap makes it easy to secure and remove the helmet, and the built-in sun visor helps mitigate sun glare during bright days.

This color option provides an equally versatile option for riders who want a coordinated look with their gear or simply prefer blue. The 3/4 open-face design prioritizes airflow and visibility while maintaining adequate coverage for everyday dirt-bike adventures and scooter riding.
Buying Guide
Safety Standards and Certifications
Look for helmets that meet recognized safety standards. In the United States, DOT FMVSS-218 is the baseline requirement, ensuring the helmet offers impact protection and an approved restraint system. Some riders in other markets also seek ECE or other regional certifications. When evaluating half helmets, verify that the certification is clearly stated on the helmet shell or accompanying documentation. The five helmets covered here all emphasize DOT certification and real-world protection for off-road and urban riding scenarios, which is critical for confidence on rough trails and busy streets.
Fit, Sizing, and Sizing Charts
Proper fit is essential for both protection and comfort. Measure the circumference of your head about one inch above the eyebrows. Brands vary in their sizing charts, so always consult the specific brand’s chart before purchasing. If you’re between sizes, it’s usually better to choose the smaller size for a snug seal around the temples and forehead. When trying on, wear the helmet with the same riding gear you’d normally use and check for even pressure around the head without pinching or gaps along the temples or around the ear area. The ILM line offers L, M, and XL options to accommodate a range of head shapes, while ZXKWFL provides a relatively universal fit for its 3/4 designs.
Shell Material and Weight
Shell construction affects impact absorption, durability, and weight. Common materials include ABS and polycarbonate blends, sometimes with fiberglass reinforcement in higher-end models. Lighter helmets reduce fatigue over long sessions but should still meet safety standards. In our selections, the ZXKWFL models emphasize lightweight design around 900 grams, which supports comfortable all-day wear. The ILM models prioritize a balanced weight with sturdy shells and ventilated interiors, offering a practical compromise between protection and comfort for dirt bike, ATV, or scooter riding.
Ventilation and Comfort
Ventilation systems help regulate temperature and reduce moisture during heated rides. Look for multi-vent designs that channel air across the crown, cheeks, and back of the head. Removable or washable liners improve hygiene and comfort for extended usage. The ILM 726X family showcases a multi-vent system designed to keep riders cool during long climbs and hot days, while the ZXKWFL helmets emphasize a lightweight, breathable interior with comfortable padding appropriate for daily commuting and casual off-road trips.
Visors, Sun Shields, and Accessories
Detachable visors or sun shields protect eyes from glare and enhance visibility in changing light conditions. Seek helmets that allow quick detachment or replacement of visors for maintenance or customization. Some models also enable compatibility with goggles, glasses, or masks, which is helpful for off-road use where dust and debris are common. The ILM 726X models feature detachable lenses and sun shields, providing flexible light control, while ZXKWFL’s retro designs incorporate quick-buckle systems and built-in visors for convenient on-the-fly adjustments.
Maintenance, Longevity, and Value
Durability and ease of maintenance impact long-term value. Removable liners, easily replaceable visors, and simple strap adjustments reduce wear over time and simplify cleaning. If you ride in dusty or muddy conditions, consider helmets with robust ventilation and washable interiors. Weight, comfort, and how the helmet holds up after repeated use are also important for longer seasons. Among our picks, both ILM and ZXKWFL emphasize practical maintenance features while delivering reliable protection for diverse riding contexts.
Use Case and Versatility
Open-face half helmets are typically favored by riders who prioritize visibility and airflow, particularly on dirt trails, go-kart tracks, or urban commutes. If you frequently switch between dirt riding and street riding, a versatile half-helmet with a detachable sun shield or visor can adapt to lighting changes without requiring multiple helmets. For riders who value a classic, retro aesthetic, the ZXKWFL Vespa models offer a distinctive style without sacrificing safety or essential features.
