What We Like: Epic safety innovation, lightweight, and well ventilated

What We Don’t: Not quite as much coverage as our other top picks

We might not have a specific title for the Leatt DBX 3.0 All Mountain, but it is right at home with the rest of our top picks in just about every category.

Leatt is a company born of innovation. The Leatt brace introduced the first mainstream neck brace to motocross and downhill sports, and now Leatt is innovating in the helmet arena as well. The Leatt DBX 3.0 All Mountain is a high coverage open face helmet that challenges the rest of our top picks in both performance and innovation.

Coverage, Weight, and Ventilation

The Leatt DBX 3.0 All Mountain helmet provides better than average coverage if not quite as much coverage as the 6D Helmets ATB 1T EVO or POC Tectal Race Spin. It provides excellent coverage on the back of the head but does not come down to cover the temples quite as well as some of our top picks for best open face mountain bike helmet.

Meanwhile, the DBX 3.0 All Mountain’s 18 vents do a great job of providing ventilation, particularly for a helmet that goes out of its way to add extra safety tech, which usually comes with a weight or ventilation penalty. And at 360g, there is also very little added weight to speak of, for the Leatt DBX 3.0’s Turbine system.

Safety Tech

As with our other top picks, the Leatt DBX 3.0 All Mountain helmet sits on the cutting edge of helmet safety technology. Like 6D Helmets and Kali Protectives, Leatt is using a technology that aims to fulfill the anti-rotational impact function of MIPS, while also increasing protection against straight on impacts. Also, like the 6D ATB-1T EVO mountain bike helmet, the Leatt DBX 3.0 is a bit larger than most helmets to accommodate for this technology. Leatt calls this technology Turbine 360.

In the case of the DBX 3.0, Leatt’s Turbine 360 system is made up of 12 “turbines.” Each of these turbines is actually a flexible, rotating, pad. Each “turbine” can flex and twist, allowing the helmet to rotate without exerting the rotational force on your head, while also absorbing impacts from whatever direction they come.

Like the 6D ATB-1T EVO’s  ODS system, this seems like an improvement over MIPS, at least in my mind. It also solves the problems that arise from sticking a third party liner in a pre-made helmet.

Finally, given its light weight and non-ventilation restricting nature, Leatt’s turbine tech might be the future of helmet safety technology, for the mountain biking world and beyond.

Other features

The Leatt DBX 3.0 All Mountain helmet features a simple visor that is easily manipulated and has no trouble accepting a pair of goggles underneath when raised. It does not feature a goggle strap, though it seems to do just fine without one.

A large dial makes adjusting the helmet’s fit easy, even with gloves. Leatt also used the Fidlock buckle on the chin strap, which we feel is a great addition to any helmet. However, the straps are not as easily adjustable around the ears as some, so getting them set up in a way that they do not rub your ears can be a pain.

Finally, the decreased temple coverage does mean that you are less likely to have problems with your sunglasses contacting the helmet than with other high coverage open face mountain bike helmets like the POC Tectal Race Spin.

The Bottom Line

I know that we are not making it terribly easy to choose, but the Leatt DBX 3.0 All Mountain helmet is yet another great mountain bike helmet. While we wish it provided just a tiny bit more temple coverage, it packs some of the most impressive new safety technology of any mountain bike helmet on the market and does so without adding much weight or sacrificing ventilation. Furthermore, at around $170, it joins the 6D Helmets ATB-1T EVO and TLD A2 MIPS helmets on the “inexpensive” end of our top picks for best mountain bike helmet of 2020. The Leatt DBX 3.0 All Mountain could easily have been our top overall pick, but we held back a little because it offered slightly less coverage than our other top choices.
