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 iXS Helmet Trigger FF MIPS is a lightweight, full-face mountain bike helmet designed for adults, making it suitable for aggressive riding styles and offering robust protection. It includes the MIPS (Multi-directional Impact Protection System) technology, which is a significant advantage for safety as it reduces rotational forces during impacts. This helmet meets the key safety certifications, ensuring it provides the necessary protection for mountain biking.

The fit ranges between 58-62cm, which fits most adult heads comfortably, and the adjustable fit system adds to the comfort. The helmet's ventilation is well-designed with multiple vents, helping keep the rider cool during intense rides. Its lightweight build, at just 1.31 pounds, reduces neck strain, making it suitable for longer rides. The visor is adjustable, providing adequate sun and debris protection while allowing for clear vision.

The padding and liner are removable and washable, which is a practical feature for maintaining hygiene. However, the chin strap and buckle are standard and may not be the most advanced in the market, potentially offering less convenience compared to magnetic buckle systems. This helmet is a solid choice for serious mountain bikers who prioritize safety and comfort during their rides.

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.
