From the biomedical engineers and medical staff of the Leatt® research labs comes a 100% new neck
brace. We believe that the 5.5 neck brace is truly the most technologically advanced neck brace
in the world. The CE certified 5.5 neck brace balances the needs of comfort, effectiveness and safety by
allowing greater freedom of movement and adjustment to more closely meet the needs of top level racers
whilst Leatt®’s commitment to safety ensures that key safety features pioneered by Leatt® are built into
The core of what makes our neck braces work is Alternative Load Path Technology (ALPT®) and for the
ALPT to work optimally neck braces must fit correctly. The adjustability built into all Leatt® neck braces is
not just for comfort, but to ensure a correct fit that assists in optimizing effectiveness of your neck brace.
We believe that no other neck brace can be adjusted to fit riders as well as a Leatt®. The front and rear
sliding SureFit adjusters can be set for your personal body shape, without tools, in less than 30 seconds.
The brace can also be readjusted as necessary for growing kids or when worn with different apparel. 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.
The 5.5 has lowered side areas, below the ear, that increases comfort and wearability, especially on kids,
smaller statured riders and riders with shorter necks. A simple pop off shoulder pad that can raise or
lower your brace to suit your neck length or helmet rim profiles. Both the front and the back feature has
the new split design that promotes broader dissipation of energy transmitted to the body and have new
molded padding for greater comfort. The semi-rigid chassis 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. If broken this strut can be purchased as a replacement part and easily changed
out. The strut is lined with the same soft padding as on all the surfaces that ride against your body and this
protective padding is on the brace edges facing inwards towards the soft tissues of the neck. The injected
foam padding is more durable and easier to clean than ever before and designed to accommodate custom

Rated 5 out of 5 Best neck brace i've tried!
So the DBX 5.5 is my third neck brace, and they just keep on getting better. i have yet to do the ultimate test on it, but i hope i wont have to, but after seeing Sam Hill's crash in world champs in Hafjell, i'd say it works excellent. I have only used Leatt braces and allways been super happy with how they preformed. they are lightweight, they do not restrict head movement too much, and they can still take a good pounding before you have to change them out. a bit expensive, but when you look at the outcome of your next potential crash, i'd say it's worth every penny!

Rated 5 out of 5 by Lestro One of the best on the market
Luckily, I haven't had to really test the brace out yet, and I don't intend too, but you don't buy one of these with the intention of testing it out to see if it works.
It's easy to get correctly fitted and it doesn't affect head movement too much either. I don't use the strap because it seems to sit there and do it's job without it.
£300 is a lot of money, but it's better to spend that once than the possibilities of a crash without one.

Rated 5 out of 5 by Cannonfodder Great brace
This is the first brace I have owned so have nothing to compare it to.
I'm really pleased with it. It's light & comfortable. I have had a little tumble where it & felt it do it's job. Yes they are a lot of money for a bit of plastic but your paying for the R&D & if it saves your life or stops you from been in a wheelchair then it worth every penny.
