10 Best Full Face Mtb Helmet 2020 2025 in the United States

The OutdoorMaster Full Face Mountain Bike Helmet is a solid choice for both men and women who are into mountain biking, BMX, or downhill racing. It offers maximum protection and comfort with its EPP collarbone impact system and chinbar shock pads. Safety is further emphasized by its fit system, accommodating head sizes from 57 to 62 cm. The helmet is designed to be lightweight, weighing just under 750 grams, and comes with 27 high-flow cooling vents to keep your head cool during intense rides.

The ventilation system is a standout feature, ensuring breathability even during long biking sessions. The visor is pivoting and helps protect your eyes from elements like the sun, wind, and rain, and is also compatible with goggles, making it versatile for different riding conditions. The removable and washable liner, along with two sets of D-rings, adds to the convenience and customization of the fit.

However, it’s important to note that the helmet might feel slightly bulky to some users due to its full-face design. The chin strap and buckle are sturdy, but they might require a bit of adjustment to get the perfect fit initially. The helmet’s construction using ABS material ensures durability, though some users might prefer a more premium material for added reassurance. This helmet is excellent for those looking for a balance of safety, comfort, and ventilation in a lightweight package. It’s particularly well-suited for avid mountain bikers who need reliable protection without compromising on comfort.

The Smith Mainline MTB helmet is designed specifically for downhill and enduro mountain biking, offering strong protection with its Koroyd material and MIPS system that help absorb impacts effectively. It meets multiple safety standards, including U.S. CPSC and ASTM downhill certifications, giving you confidence on serious trails. Ventilation is handled well with 21 vents that keep air flowing to reduce heat and prevent your goggles or glasses from fogging up.

The helmet is fairly lightweight for its category, but at 3.2 pounds, it is a bit heavier than standard trail helmets—this is common for full-face models designed for high protection. Comfort is a highlight, with several washable padding options (cheek pads, crown liners, and neck rolls) to customize the fit, plus a three-position adjustable visor to block sun or debris. The chin strap uses low-bulk webbing and a secure buckle, which should stay snug without causing discomfort.

A notable consideration is the helmet's bulk and weight, which might feel noticeable on longer rides; however, this trade-off comes with the added protection downhill riders need. The Smith Mainline suits riders looking for a high-safety, ventilated, and comfortable helmet to push their limits on aggressive mountain biking.

The Bell Sanction 2 DLX MIPS is a solid choice for adult downhill mountain bikers and BMX riders looking for full-face protection. It meets important safety standards including CPSC for bike helmets and ASTM certifications for downhill and BMX, giving you confidence in its protective ability. A standout safety feature is the MIPS technology inside, which helps reduce rotational forces during impacts, enhancing your head protection.

Comfort-wise, the helmet offers Ionic+ padding that adapts well to your head shape and a flexible Flying Bridge visor that improves airflow around your face, helping to keep you cooler on long or intense rides. The helmet's ventilation benefits from this design, allowing good air circulation despite the full-face coverage. Weight is reasonable at about 1 pound, which is light enough for aggressive riding without feeling bulky. The adjustable chin strap and buckle system are straightforward and secure, adding to the helmet’s comfort and fit.

A minor drawback is the sizing, which requires careful measurement since fit is critical with full-face helmets; improper fit reduces safety and comfort. Also, while the visor design enhances airflow and impact absorption, some riders might prefer a more traditional visor for easier replacement or adjustment. The Bell Sanction 2 DLX MIPS blends safety, comfort, and ventilation effectively, making it a reliable helmet for serious mountain biking and BMX riding, especially if you prioritize advanced impact protection and versatility across different terrains.
