The Good: Comfortable, no straps needed, its blue, removable pads, saves your neck
The Bad: It broke my collar bone
Ok, I know that "The Bad" sounds like a bad thing but really it's not when put into context because the thing probably did a lot to save my neck.
I had a season ending crash at one of our local downhill trails near Portland OR and among the many injuries that put me in the hospital for four days was a broken collar bone. Three different doctors all concluded, independently, based on my description of the fall that the brake was from a direct downward force to my right clavicle. Given the way i fell on my right side it had to be my helmet that pressed down into the brace that broke my collar bone. From what I understand this isn't unheard of and it sounds like Leatt has made some adjustments to the DBX Comp 4 brace to help mitigate this. Another solution to help limit the chance of a collar bone brake would be to wear proper armor underneath the brace so it distributes the load better. My buddy Gene uses a POC VPD 2.0 suit and says he never feels the brace pushing on him.
I want you to take that experience with a grain of salt however because as my review title suggests, I'm a hack and crash often. More often than not this brace has done its job, as it may have in my season ender. This experience has not discouraged me from wearing my brace at all. It did however make me revisit my thoughts on how little torso protection I wear.
Overall I suggest you get one of these. I read a report from Whistler saying that head/neck injuries were the 2nd most common at the bike park only after shoulder injuries. They do take some time to get used to and I suggest getting them fit properly. Take your time fitting it, watch the videos and even call Leatt for help. Since it does limit your head movement you'll find yourself looking down trail by moving your eyeballs up rather than tilting your head up. Originally I was getting headaches from this (I know, I'm a bag of problems) but this changed when I replaced my Moto GPX brace with this DBX one. This brace allows for further adjustment on the rear support to give you a bit more range of motion. In addition I believe fit was improved because I also changed from a helmet that wasn't designed with the brace in mind to a D3 which is.
In a nutshell, protect yourself so you can keep riding well past your 50's.
I've fallen and I can't get up.
