Protect ya neck.

Nobody wants to think about the possibility of a catastrophic neck injury, but thankfully, the good folks at Leatt have taken a hard look at this most undesirable of unintended consequences. And while the DBX series has long been the benchmark in comfortable, functional neck protection, Leatt’s latest creation, the DBX 5.5 offers up more adjustability than ever before, which means even more riders can achieve a perfect fit in the quest for safety.

The point of the DBX brace is to limit the range of motion in your neck, reducing over-extension injuries. To that end, a fiberglass-reinforced polyamide chassis radiates out from around the neck, blocking further motion once the helmet has bottomed out. But as you are probably aware, while fighting hyperextension is essential, it’s perhaps equally important that the brace doesn't inhibit your required range of motion. After all, if the brace reduced your ability to look down the trail, it could be just as dangerous as not wearing it in the first place. But fine-tuning is precisely what makes the DBX 5.5 even more advanced than its predecessors, which means you get the protective qualities of the brace, without sacrificing freedom of motion.

As with previous generations of the DBX, the 5.5 has an adjustable opening to help it accommodate a large range of body types. Also carrying over are the shoulder pads, which allow you to raise or lower the brace to accommodate for different neck lengths. Coming from the Pro series is the adjustable aft wing, which is particularly important for riders whose style is based around a flattened back, as opposed to a more upright posture. And while the rear thoracic brace is featured on all DBX braces, the 5.5 utilizes a brand new split brace, which is adjustable to one of four angle settings. The split brace enhances comfort, and like previous iterations, it’s designed to snap off, before imparting excess pressure on the spine. In snapping, the brace is designed to dissipate the majority of energy, keeping your spine intact in a manner that’s akin to the protection afforded by an EPS foam helmet.

The fit of the DBX 5.5 has also been refined, with lowered side wings to enhance lateral freedom. It’s particularly important for smaller riders, or those with shorter necks. And for those who fall outside the aforementioned categories, it works in conjunction with the variable height shoulder pads to allow you to tailor the fit. While the original DBX series was undoubtedly a revolution in off-road safety equipment, we’re confident in saying that the DBX 5.5 is a worthy successor to the benchmark that it’s replacing.

The Leatt DBX 5.5 neck brace is available in two sizes, from Small/medium to Large/x-large, and in the colors Black, Green/black, Red/black, and White/black. Please note: Like all neck braces, the Leatt DBX series requires the use of a full face helmet in order to provide protection.

Simply the best!

  • Familiarity: I've put it through the wringer

I have been a fan of Leatt braces for years and have worn the DBX for as long as I can remember. The old design was excellent but I always had issues with the fit not being perfect. That has all changed with this one. The lower profile makes helmet clearance a non issue and the adjustments are much improved. My kid wouldn't wear the old style but he wont take this one off. He doesn't even know it is on him.
So do they work? I have had two friends crash head first while wearing Leatts and they both walked away with nothing more than a scratched helmet. So I would say yeah they work. Bottom line is buy one of these. There is no reason not to.
