Happy Customer This offers the highest level of protection from alpinestars back protectors. I wear this under my Stella T-GP jacket. It has great adjustability, it's comfortable in riding position, allows decent airflow even with my jacket on over it. I ordered a Medium but probably could've gotten away with wearing a small. I'm 5'10, and the Medium offers full coverage from the base of my neck to the start of my butt. When standing it digs a little onto the top of my butt cheeks, but when in riding position it feels and fits great. The Small might have been a bit more comfortable when standing/walking but would've offered slightly less coverage. Since I typically take my gear off once I'm parked I'd rather have a little more coverage while riding than comfort while off the bike. March 25, 2014
This product has great features this is the same guard column, I refer to all the Alpinestars brand. January 20, 2014
works Looks cool, seems to be mainly pretty good, comfy dont really notice it on. December 28, 2013
Thin but great protection The Bionic protector is a nice, thin item that is nonetheless rated to level 2 CE protection. It fits very well under a Atem race suit (as it should, of course) and provides good coverage. The venting is quite good, too. November 21, 2013
Solid Choice for Back Protection Very happy with the Bionic back protector. Superior level of protection versus the existing foam inserts in my two jackets. I pulled the foam padding out and jacket fits comfortably over the Bionic. Not restrictive or too bulky. Forget it's there by the time I get to the end of the street. Wearing it every time out - ATGATT. Wish it was a little less expensive to be well protected and cannot speak to durability yet, but seems like typical Astars quality product. 05 FZ6 November 18, 2013
Great protector used by pros This is a great Level 2 protector. I use it with the Bionic Air Protector depending on where I'm riding. It's definitely hotter because of the strap around your waist and stomach. But it provides much more coverage than the protector inserts. It's very light and well built. Sizing - I usually wear Medium A/S gear but had to order Small. The waist strap is tight but it's not supposed to be loose. I'm going to probably use this for track duty mostly with the Bionic Air for street use even though it's only Level 1 and doesn't provide as much back coverage. I think you should have both if you ride the street and track. July 15, 2013
Everyday Protection Ordered this for use on the track but now I it only makes sense to ride with it (and a chest protector). Comfortable, straps keep movement to a minimum and it feels like how A* quality should be. This is my first back protector but I think I made a good choice. April 24, 2013
Excellent back protector, velcro is poor Very confident inspiring back protector. Nice design, great fit. Slightly hot in hottest summer days. The only thing that they need to address is the Velcro, for most people I know, it barely last a summer before if doesn't grip enough to hold together. That said I like it so much I'll just have some quality velcro installed on it and should be good for a few more seasons. March 27, 2013

A shopper asked: I'm new to the motorcycling world and I was just doing some research on what things to get with my motorcycle jacket. I decided to go with the Alpinestar Jaws Perforated Leather Jacket. My friends have all recommended that I get a back protector. My question is: With this Bionic Back Protector, do you have to wear it first and then put your motorcycle jacket over it or can you remove the straps and place the armor piece into the pocket that is located in the back of the motorcycle jacket?

David S: You have to wear it first then put your jacket on. With this back protector the tail of it covers your tail bone. Because of the length it will not fit inside your jackets back protector pocket area. I myself have a separate back protector that goes in the pocket area of my riding jacket. I went with Dainese Shield Air G Level 2 Back Protector. Its comfortable. It fits well. I also have an alpinestar jacket so don't worry, just because the brands are different does not mean it won't fit but you can go with an alpinestar protector. The Bionic Back Protector I use to go under my race suit. Mar 18, 2014

Javier S: This is a standalone back protector. If you are getting an Alpinestars leather jacket, or something comparable, most will be able to accept a clip in version of this back protector or one that slides into a sleeve in the jacket. Jut focus on the ones that don?t have any backpack or Velcro looking straps to them. Mar 17, 2014

A s: This one in particular is designed to be worn by itself and under the jacket. If you want something for the jacket pocket, buy something else.
These are better in my opinion.

John M: You put it on first, and then the jacket goes over it. You will probably get a bit more coverage with this back protector than the insert. The insert is more convenient. Mar 17, 2014

A shopper asked: What CE rating is of a higher level of protection for this back protector, CE Level 1 or CE Level 2? I am 5'5, what size would I use? Feb 10, 2014

Katie N: CE Level 2 offers a better level of protection.

I'm 5'10, I ordered a Medium and I'm satisfied with the fit. It definitely offers full coverage for me all the way from my upper back just below the start of my neck, all the way down to the low back just above the curve of my glutes. In riding position with a slight forward curve to my posture it fits and feels great. When standing straight up I can feel that it is just shy of being too big in length because the tailbone section of the back protector pushes onto the top of my butt cheeks a little. Not a big deal and once I'm off my bike standing/walking I will typically take my gear off anyway.

I'm not sure how much smaller in length the size Small is from the Medium but I think I could've fit that as well, perhaps a little more comfortably while standing and being more upright, but I'd rather have slightly more coverage while riding than comfort while off the bike. And in riding position the fit is great and comfortable.

Javier S: I?m about 5'7" and purchased this in a Medium. It fits very well. I tried on a few others while in the store including one that you could adjust the position of the waist band, but none fit as well as the Alpinestars back protectors. I almost purchased the Alpinestars Bionic Air back protector which is a hair thinner than the race one, but the Air was only CE1 rated. This one, the Alpinestars Bionic Back Protector is CE2 rated, which is a higher rating. The medium should fit you well if you are 5'5". Feb 12, 2014

Errol G asked: Is this thinner that the spidi warrior evo back protector? I'm torn between this and the spidi on which one to get. Which one is better? Sep 21, 2013

John M: I don't know if it's thinner, but I've had the a-stars protector for nearly a year, and I wear it every time I get on my bike. I don't really notice that it's there, but it does add a couple of degrees on really hot days. That's probably true for any back protector. Highly recommend. Sep 21, 2013

A s: Hi Errol,
I haven't seen the other one. The only one I have seen is the shox model which is thinner, but I like the alpine stars one, I would recommend it if you are asking for my opinion.
