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 11 11
Why ride without one? Integrates really well with Leatt 5.5 HD pro armor...no need for the straps...slides right into receiver slots both front and back; and there it stays until you press the release button and take it off. Well thought out. I did tape on a little piece of 7/8" thick foam on each side--where the rubber pads rest on my shoulders. I'm a bit of a long necked geek--and I wanted the helmet and brace to make contact earlier. Got used to it in minutes and now I don't even notice that it's there. I was concerned about wearing it with the jacket...and it is a compromise. But I just zip up as far as I can get my jacket to go and sort of tuck it in around the brace. Not perfect--but not too bad. I don't ride that much in the rain. YMMV. Pretty cheap insurance... June 13, 2016
Save your neck use this Fits perfectly and not even noticed while riding. Great price and service from RevZilla July 26, 2016
Great product at a great price Neck brace technology has come a long ways in the last 10 years and Dr. Leatt has been the pioneer of many of the advancements. You can find every detail on how this neck brace is tested and verified to work on Leatts website. I had a serious accident several years ago where I injured my neck which I believe could have been avoided with this neck brace. $300-$400 is a minor investment to protect your neck and your quality of life. Compared to other manufacturers in my opinion the Leatt is the most comfortable. The fit and finish is also excellent. I'm using this neck brace with the Fox Airframe chest protector and it works perfectly with it. June 7, 2016
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 .

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
