10 Best Dual Sport Helmets 2025 in the United States

The Oneal 2021 Sierra II Adventure Dual Sport Helmet is designed to cater to riders who enjoy both on-road and off-road adventures. With a shell made from ABS, it offers a decent level of protection, and its weight of approximately 1590 grams is fairly manageable for long rides. One of its standout features is the ventilation system, which includes a high air intake mouth vent that allows for airflow while keeping dirt out, making it suitable for varied conditions. The integrated face shield is another plus, providing additional protection against wind and debris.

Comfort is important in a helmet, and this model does well with a moisture-wicking, removable liner that can be washed, ensuring a fresh experience on each ride. The padded chin strap with a double-D safety lock enhances the secure fit, which is crucial for safety. However, some users might find the universal fit less comfortable if they have a very specific head shape or size.

On the downside, the noise reduction capability might not satisfy everyone, especially at higher speeds where wind noise can be more prominent. The helmet's composite material is robust but could be heavier than some premium options available on the market. Additionally, the styling is somewhat basic with its flat black finish, which may not appeal to those looking for more vibrant or flashy designs. This helmet would particularly benefit riders who use their motorcycles or ATVs for both street cruising and off-road adventures, providing a versatile option that doesn't compromise on safety or comfort.

The O'Neal Sierra Helmet is a solid choice for dual-sport riders who want reliable safety and practical features. It meets important safety standards (DOT and ECE 22.05), offering good protection on the road or trail. The helmet’s shell is made from polycarbonate and ABS, materials known for their strength and impact resistance. Weighing just 250 grams, it’s quite lightweight, which helps reduce neck strain during longer rides. For comfort, it includes a padded chin strap with a secure double-D lock and a height-adjustable integrated face shield that shields your face from wind and debris.

The aerodynamic shape and integrated shield contribute to airflow design, though it may not provide as much ventilation as helmets specifically designed for hot weather. The visor is adjustable, which is handy for different lighting and riding conditions. While noise reduction is not a prominent feature, some wind noise may be noticeable at higher speeds. The glossy finish adds a nice look, and the helmet fits a range of adult users with its large size and unisex design.

If you’re after a dependable helmet for both off-road and on-road riding that balances safety, comfort, and style without adding extra bulk, the O'Neal Sierra fits well. For those prioritizing advanced ventilation or noise-canceling features, exploring other options may be beneficial.

The ILM Motorcycle Dual Visor Flip-up Modular Full Face Helmet in Matte Black is a solid choice for riders looking for a balance of safety and convenience. It meets FMVSS-218 and DOT safety standards, ensuring good protection. The helmet's outer shell is made from high-resistance ABS material, which is known for its durability and impact resistance. Weighing 4.5 pounds, it might feel a bit heavy for some users over long rides. However, the modular flip-up function adds convenience, allowing riders to easily switch between full-face protection and an open-face setup.

The helmet comes with a clear visor that is anti-scratch and anti-fog, providing a wide view, which is a vital feature for safe riding in various weather conditions. Ventilation is well addressed with six vents, helping to keep the interior cool and comfortable. The interior liner and cheek pads are lightweight, soft, and easily removable for washing, which is a plus for hygiene. However, the noise reduction capability, while better than some helmets, may still not be sufficient for those highly sensitive to wind noise.

The fit is adjustable with a micrometrically adjustable strap, and the helmet includes a snap closure for added security. Its sleek and aerodynamic design reduces wind resistance, contributing to a quieter ride. If you find the initial fit uncomfortable, the manufacturer offers additional liners to improve comfort. The ILM 902 model is a versatile and reliable helmet, particularly beneficial for riders who value modular functionality and safety compliance.
