Early last spring, when Leatt burst into the adventure gear market with a full line of quality jackets, pants, boots and gloves, there was assurance that a premium helmet was on the way to cap off the works. Finally, we have the full details of Leatt’s adventure helmet line, available in a 9.5 Carbon and 8.5 composite model, due to arrive at dealers in January 2025.

In keeping with the storyline of the brand’s successful MX helmet line, the ADV lids are sold as “kits” (we’ll get to this later) with both budget-minded and top-end options. Let’s  get into the details, beginning with their differences. 

As you might expect, the 9.5 Carbon is the more exclusive model, featuring a six-layer carbon matrix compared to the 8.5’s three-layer composite construction. The slightly stiffer Carbon version achieves a weight reduction of nearly two ounces, bringing its total weight to 3.28 pounds (M/L), compared to the 8.5 composite’s 3.47 pounds (M/L). Both helmets surpass ECE22.06 and DOT safety standards. 

The 9.5 Carbon also features a magnetic Fidlock buckle closure, offering a modern alternative to the traditional double D-rings used on the 8.5 to secure its chin strap. It also includes a convenient carrying case with dedicated compartments to neatly store all the accessories that come with the helmet.  

Now that we’ve covered the differences, let’s dive into the complete package both helmets offer, starting with the impressive “kit” element. Both models come loaded with extras, including a polychromatic full-face shield that automatically adapts to changing light conditions. As a bonus the kit includes a clear shield that can be swapped out quickly and without tools. 

In addition to the two included shields, Leatt provides a wide-angle Pinlock 120XLT MaxVision Lens to combat shield fogging on humid days, as well as its 4.5 goggle—an off-road essential the company describes as “bulletproof.” Notably, the 4.5 goggle included with the 9.5 package features a premium Iridium-finish “Iriz” lens, said to offer superior adaptability in varying light conditions compared to the clear lens provided with the 8.5’s accessory goggle.

Having all these options gives riders the flexibility to customize their setup based on their plans. If you’re riding full-time on-road, simply remove the peak and use one of the two full shields for a streamlined experience. For a mix of on- and off-road riding, grab the accessory goggles but leave the shield in place—the helmet is designed to accommodate goggles with the shield either open or closed. Planning a full day of off-road adventure? Remove the shield and snap in the included covers to cap the empty mounting points (and don’t worry, they include extras in case you lose one).

As expected from Leatt, safety features are front and center, starting with an extra-wide eye port designed for optimal peripheral vision. On the more advanced side, Leatt incorporates its patented 360° Turbine Technology, a unique, alternative Multi-directional Impact Protection System (MIPS).  Leatt’s version of MIPS uses small, disc-shaped “turbines” made from an energy-absorbing polymer, strategically placed within the ADV helmet’s interior, which incorporates four densities of impact foam. These turbines are engineered to deform and rotate slightly upon impact, reducing rotational forces on the brain.

While traditional MIPS works by introducing a low-friction layer between the helmet’s shell and the foam liner to allow slight movement and reduce rotational forces, Leatt’s turbine system goes a step further. It not only addresses rotational impacts but also absorbs energy from both high- and low-velocity impacts, offering enhanced protection and potentially reducing the risk of concussion-related injuries.

Another well-thought-out safety feature is the removable cheek pads, which can be quickly released from the ADV helmet’s shell in the event of a debilitating crash. A clear yet discreet message on the shell’s edge, just above the bottom of each cheek pad, informs first responders to pull red webbed micro straps in order to quickly remove the cheek pads, allowing for safe removal of the helmet.

In terms of comfort, Leatt conducted extensive wind tunnel testing to design an optimal shell shape, claiming it reduces lift by 38% and drag by 8% compared to other “benchmark” helmets. This result should enhance stability by minimizing neck strain and head buffeting. 

Ventilation is achieved via a large chin vent with two exhaust vents on either side of the jawline, as well as two intake vents above the brow, with their own exhaust vents on the top rear of the helmet, while two exhaust vents on the lower back of the helmet provide additional heat dissipation. Both helmet versions include a removable chin curtain, and the liners are pre-molded to accommodate speakers, with internal channeling to keep wires neatly concealed.

When Leatt’s new ADV helmets hit the market, they will be available in sizes XS to XXL, spread across three shell sizes. A wide range of accessory cheek pad thicknesses are also available to fine tune the fit. The 8.5 composite version will come in a variety of colors, including Hi-Viz and a red, white, and blue “Royal” design. As expected, the 9.5 Carbon features a sleek carbon-fiber-inspired gloss black and ghosted grey finish.

For added peace of mind, in addition to a standard one year warranty, these new helmets are included in Leatt’s crash replacement program, which provides discounts on a replacement unit in the event the original helmet is damaged during riding. 

When it comes to pricing, the 9.5 Carbon retails for $799, while the 8.5 is priced at $599, which is inline with other high-end adventure helmet offerings and a reasonable ask considering the advanced safety technology, included goggles and additional convenience features. We plan to test one of these units soon so stay tuned for more details on how it performs.
