The Leatt DBX 5.5 Junior MTB Neck Brace is a Parent's Commitment to Their Child's Safety

So your child is brave and daring. Soccer, basketball or swimming wasn't their sport of choice. They love the hills, trails or jumps and the feeling they get when they are out on an incredible ride, but as a parent, it can make you sick with worry. How do you allow your kid to enjoy their passion if you are worried out of your mind? The answer: protective gear and no company has the years of intensive research and a proven track record like Leatt. We are both riders and parents here at SportsProtective. Not only do we trust Leatt and their gear for ourselves, but for our families as well. 

Leatt is known for their revolutionary neck and spine protective gear. The Leatt 5.5 neck brace is one of the most technologically advanced and trusted braces on the market. So a company filled with bright people did what you would expect. Took the incredible innovation of the 5.5 and scaled it down to fit junior riders, giving them the same protection and safety expectations of their adult model. We think the Leatt DBX 5.5 Junior Neck Brace is an excellent product that is worth its weight in gold. We wouldn't send our kids out to ride without it. 

Load Path Technology - What separates Leatt from their competitors? Simply put, it's Leatt's patented Load Path Technology. Used on all Leatt neck braces, Load Path Technology spares your neck and back from absorbing all the energy of a blow. Instead, the neck brace intercepts the impact from the skull by dispersing the force, thus sparing you from a more serious, potentially season-ending neck injury. Working in conjunction with a full face helmet, the neck brace guards against extreme backward-bending of the head (hyper-extension); extreme forward bending of the head (hyperflexion); and over-bending of the head to either side (lateral hyperflexion). Additionally, the neck brace is protective when the chin bar takes the brunt of a face plant and pushes the neck backward (posterior hypertranslation). In certain scenarios, the neck brace can prevent axial loading.

Fit and Adjustability - The Leatt 5.5 Junior has excellent ease of use. It allows for faster, toolless adjustability to ensure the right fit, compared to other braces on the market that require an Allen wrench. The 5.5 Junior has a much quicker and efficient sliding front and rear SureFit adjusters that are ideal for constantly growing youths. The adjustment latch snaps into place and can be resized in seconds. The FlexCore thoracic strut has 0,5,10 and 15-degree adjustable rubber spacers to allow for a more precise fit to the rider's back. We love how easy the 5.5 Junior is to adjust and fit. The brace won't be an annoyance or a headache to your child while riding and for you, the parent, the constant headache of worry you felt will be alleviated too.  

About Leatt

Sometimes it takes a tragedy to create change. Such was the case in South Africa in 2001 when Dr. Chris Leatt, a medical doctor and motorcycle rider, went to a racetrack with his son who himself had just begun to ride. There, Dr. Leatt witnessed the death of another rider, Alan Selby, from suspected neck injuries. Dr. Leatt was so shaken by the incident that he made it his mission to develop a device that would go a substantial way toward preventing this type of fatal injury in the future. After three years of research, development, and testing, Dr. Leatt introduced his first Leatt-Brace. However, it would be another two years before the Leatt-Brace would make it to market on a large scale. Today, Leatt-Brace is a worldwide leader in neck protection for extreme sports. Dr. Leatt likes to say the Leatt Brace is "a helmet for your neck." Designers and engineers in the Leatt laboratory in South Africa have expanded their reach to high-technology protective armor that meets varying needs of downhill mountain bikers, bmx bikers, and skiers and snowboarders.
