Leatt GPX 5.5 Neck Brace

Leatt believes that the 5.5 Neck Brace is 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 each brace.

The core of what makes Leatt neck braces work is Alternative Load Path Technology (ALPT), and for the ALPT to work optimall, 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. 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 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 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 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 sticker kits.

Leatt GPX 5.5 Neck Brace 4.8 5 8 8
Easy to Get On & Off I purchased my GPX 5.5 neck brace for adventure riding. Both on my big bike and smaller WR250R. I can get the Leatt to work with my body armor and jacket over body armor. Easy to get the neck brace on and off. Since posting these photos, I have lowered the neck brace to sit flatter on my shoulder. I have yet to experience a fall with it and hope I never have to . May 23, 2016
hope I never need it but like have any insurance The person I spoke to at RevZilla Kevin was extremely helpful. The product was delivered the day after the order. November 23, 2015
wonderful fit, finish, and feeling of safety After watching some crashes on youtube, and having worked on numerous neck injuries as a massage therapist I was looking for some insurance while dirt riding. This Leatt neck brace fits my needs perfectly. Great materials, fit, finish, ease of use, and feelings of safety while riding. Have not crashed yet and hope not too, but who knows whats around the next corner. I am 195 lbs. and 6 ft. and the lrg. size fits perfectly out of the box. Fits well with my Leatt body protector; and you get what you pay for. November 9, 2015
great product Great but fits great i feel protected with it on! Easy to use and great look! March 9, 2015
Great product and much improved over previous versions I found this neckbrace to be very easy to set up requires no tools for adjustment and is extremely lightweight and comfortable over previous versions. The push button release is very handy and makes putting the brace on and off much easier I would recommend this neckbrace over any other. November 25, 2014
A better widget I owned an earlier model and "Fly" emblazened version of the Leatt neck brace. This one is certainly more user friendly. It is lighter overall. The folding rear strut makes good sense and is easily adjusted for back angle. Overall adjustability is very much improved on this unit. It integrates with the 5.5 Pro HD armor nicely. June 30, 2014
Haven't had a neck snapping crash This is the type of product that is better reviewed by an independent lap, not some rider behind a keyboard. June 30, 2014
Inexpensive protection When you think about it! $300+ isn't really all that much to help protect you from what otherwise would be a life changing experience . I've spent more on a part for a bike, I'm thinking my neck is worth it... May 19, 2014
