Leatt DBX 5.5 Neck Brace

Leatt DBX 5.5 Neck Brace

No introduction is necessary for Leatt DBX neck braces. Then again, the DBX 5.5 is not like other Leatt DBX neck braces. The DBX 5.5 is CE certified and balances the needs of comfort, effectiveness and safety by allowing greater freedom of movement and adjustment to meet the demands of top level racers and provide the best safety possible. The DBX 5.5 neck brace accomplishes this through Leatt’s Alternative Load Path Technology (ALPT®), which in order to work properly the neck brace must first fit correctly.

Highly adjustable fit is achieved through the front and rear sliding SureFit adjusters that can be easily set for your personal body shape, without tools, and in less than 30 seconds. To further optimize fit, the new and improved CoreFlex rear thoracic strut has an exclusive feature that allows it to be adjusted to 4 setting angles. This is done with a simple elastomeric bumper that can be set at 0, 5, 10 or 15 degrees in seconds.

To achieve superior comfort, the DBX 5.5 has lowered side areas below the ear, which enhance wearability prolong comfort. A simple pop off shoulder pad allows you to raise or lower your brace in order suit your neck length or helmet rim profiles. Both the front and the back feature have the new split design which promotes broader dissipation of energy transmitted to the body, as well as new molded padding for greater comfort.

Lastly, and more importantly, maximum safety is accomplished through a semi-rigid chassis that is flexible and adjustable enough to fit most riders’ body shape while the structure remains rigid enough to help transmit energy during an impact, while multiple engineered fracture points and crumple zones will bend or break away at pre-determined stress levels to help contribute to a riders’ safety. The new and improved CoreFlex rear thoracic strut is more comfortable than ever and still has the engineered fracture point at the top that allows it to break away in certain severe impacts. The strut, as well as the brace edges facing inwards towards the soft tissues of the neck, are lined with injected soft, yet durable foam padding.

Boasting comfort, functionality and safety, it’s no wonder why the DBX 5.5 just might be the most technologically advanced neck brace ever produced. Its looks aren’t too shabby either….

Love the brace. It's comfortable, and quickly forgotten about when riding. I bought this brace for riding more aggressive areas like Snow Summit, etc. it's one of those things that, you probably won't need, but it's nice to have for that added protection. First time wearing it, I crashed pretty hard, fracturing my ribs. My helmet received some damage, and this brace may have saved my neck. Would I have been hurt even more without the brace, I don't know. But I'm glad I didn't have to find out the hat way.

PROS: Lightweight, Durable

BEST USES: Extreme Sports, Mountain Biking

The best you can get under $350
I really like this brace. It took me about 2 minutes to get used to. I spent a good 40 minutes getting it just perfect; the adjustable in every direction is great. I don't use the straps and it stays put just fine.

Of note, I've seen some of my riding buddies use cheaper neck braces, and struggle with them fitting right. Do yourself a favor and buy a good one. Otherwise you will buy a cheap one first, then scrap it and buy a Leatt.

PROS: Lightweight, Durable

Comfortable and the fit was right straight out of the box. I hope to never need this brace but its good peace of mind having it. Also, this brace fits well with my camelback hydration pack.

PROS: Durable, Lightweight, Versatile

Great protection and well made product
Takes a little time to achieve proper fit, but once you get it, it's fine. Straps could be a little more secure, tend to loosen up (easy fix with velcro). Overall awesome product, really well engineered and designed.

PROS: Lightweight, Easy to wear

CONS: Straps Loosen Up, Straps Could Be Tougher

excelente proteccion de cuello
he tenido la oportunidad de utilizar varias protecciones de cuello, pero hasta el momento esta es la mejor, recomiendo la de plastico, pues la diferencia con la de carbono es muy alta y no hay mucha diferencia en el peso
