Leatt GPX Five.Five 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.

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

Donald K: Great neck brace, good fit and works with several chest protectors Nov 14, 2015
James M: Since I believe in ATGATT, this was the last piece to my preparation puzzle. I expect it to work fine whether roasting the pavement on the K1300S, or pounding through the wilderness on the KLR650. Jul 31, 2015
Charles C: I choose this item because I am one year new to motocross and do not have a neck brace. I have done my research and the Leatt 5.5 seems to be the best neck brace for me and in my price range. Oct 6, 2014
Jessica C: adjustability and colors to match my bike Aug 26, 2014
proctor m: protection and reputation Aug 2, 2014
Jay J: I owned an earlier version. This one shows many new refinements in fit and function. Much easier to adjust than prior versions. Integrates with the 5.5 HD Pro Chesty very well. Jul 16, 2014
A shopper asked: I am looking for a neck brace that would work with both my off-road body armor and my Aerostich riding suit. Is this brace worn over your gear and do you think it would work with both types of riding suits? Jun 19, 2015

David D: It's OK worn over cloth like material but I don't think it should go over other armor. Jun 30, 2015

John A asked: How does this brace, or a similar style work with jackets like the Klim Badlands that have large back protectors in them? Concerned that the rear support of the brace would sit on top of the back protector of the jacket. Also saw the note that the street brace is not recommended for Dual Sport helmets, any issue with this brace and an Arai XD4? Mar 16, 2014

David M: I have I believe C- Rated armor in my leather jackets. I had a serious neck operation and my surgeon review the necke brace and said this might save me from breaking my neck. Of course there's no guarantee that a serious accident might still be harmful. But this brace fits perfect a lot of adjustability. If I was able I would show you a picture of my x-ray. I myself highly recommend this brace. Mar 20, 2014

Gary R: I wear my Klim jersey over it. I had to order it 2 sizes larger to fit over my chest protection (Leatt 5.0) and my neck brace the (Leatt 5.5) Hope that helps. Buy them 2 sizes larger. You can wear the neck brace by itself on top of your jersey. I see it a lot. Glad your wearing one, it saved me a few times this year alone. Oct 13, 2015
Reply to Gary Good answer? Yes (0) No (0)
Cameron C: I don't believe that you could wear a jersey over this. It's big and high, you'd look like a frankenstein. Everyone wears their neck brace over their jersey that I've seen and I do the same. Great product though. I've had a big crash and it worked great. Oct 13, 2015
Reply to Cameron Good answer? Yes (0) No (0)
richard k: I think any jersey will work. The brace has a wide range of adjustability. I can even wear mine over a Klim jacket. Oct 13, 2015

Laurie B asked: Does anyone know how much the GPX 5.5 neck brace weighs? I see the new GPX 6.5 is partially carbon and weighs 600 grams (21 ounces or ~1.4 pounds) so how much heavier is the older 5.5 model? Thanks! Oct 15, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Jay J: In short......I'm not sure how much it weighs......that said, I just wore it (integrated with the 5.5 upper body armour) for two days and weight was a non issue. Were it something supported by the head and neck....then I'd be more concerned.

I owned an older Leatt brace (DBX) that was a ton bulkier and restrictive to movement in comparison with the 5.5......

If you have deep pockets...go for the carbon...why not?

proctor m: Mine weighs 2 lbs, 13.25 oz (1283 grams) without the supplementary shoulder pad inserts - so over 2x as much as the listed weight of the carbon fiber model. However, I don't even notice the weight when I'm riding so for me, the carbon model wouldn't be worth the extra cost. Hope this helps.

Khalid K: on their website they say it weighs 1.7 lbs compared to the 6.5's 1.3 lbs...thats barely anything. Nov 11, 2015
Laurie B: Thank you, proctor m, for weighing your 5.5 and posting the results! Wow, 2x the carbon 6.5 weight. It's good to hear that you don't even notice the neck brace weight anyway.
