Alpinestars Bionic SP Vest 4.5 5 10 10
Great for summer and winter seasons For the overall price, the item is great and provides solid protection for the back. The front could use a little bit more beefing up, though. As for size, I would say it fits true to size. The adjustable straps make it universal depending on the build of the person wearing it. It works great for the brutal hot summer days when a jacket is not tolerable. This vest provides just enough protection and the mesh is great for airflow. Likewise, this vest works great for the cold winter days because you can literally wear it under your winter coat/jacket. It is slim and wont be visible while wearing. December 1, 2015
Great product I was happy to upgrade my back protector to the Bionic SP Vest. The protection feels solid yet versatile via the zip ups built into the unit. Excited to wear it under my track suit soon! September 16, 2015
Good protection Nice way to consolidate protection under a jacket or leathers. Comfortable and stays in place. July 15, 2013
Great vest This thing is great. Let's u wear all your jackets without a back protector and ads the chest and side protection too. The mesh is a great touch. U forget u have it on and the airflow is excellent. No cons for me, just a big thumbs up. I'm 6'6" 245lbs muscular build, bought an XL and it fits perfect, not too tight, not too loose. I like the protection and feel without the bulk. Perfect. And obviously, Zilla is by far the best on the market so no doubt i'll be back for more stuff March 26, 2013
The best protector out of three I have used so far Great quality and service. It is the third time that I buy from them either directly or through someone. Thanks for everything. June 22, 2012
Great Hard Back Protection The fit and finnish is great. As well as adjustability. I purchased XL and I'm 6' 210lbs, with a relativly flat mid section and bigger chest. It's mesh so the air flow is ample. The back protector is similar if not identical to the other "bionic" back protectors offered by AS. The back piece un-zips but can not be worn seperatly. The chest pieces are a thin plastic with foam behind them and do not come off. The so called kidney pads are nothing more than thin foam. So, what's my opinion? It's a really good product to wear under a leather race suit. Very comfortable and easy to get on and off. In between track sessions I can easily unzip my suit front to cool off. If it's really hot I can remove my one piece leather suit top (let the top hang) and I don't have to mess with my back protecter since it is not connected. I've worn it all day at the track without taking it off and had no issues and stayed cool. I didn't want to hassle with the other AS offering with bottom strap and odd top "button" that connects into my leathers. Mainly since it seamed complicated to get on and off. Also I didn't go with the suspenders option since the price is so close to this model and I wanted the extra (if any) chest protection the vest offers as well as easy on/off capability.

Excellent! Because a backbone protector is not long, this is usable under most jackets. I OK it even if I wear it on a T-shirt in hot and humid summer in Japan! Is told to resemble "Madmax" by everybody,; but ... June 13, 2011
Great vest! Cons: The back protector unzips, BUT it does not unzip to the point where I can insert it into a jacket (the side velcro panels stay attached), which is a big downside. In fact, unzipped, I don't see any use at all for the back protector. This is inconvenient mainly because I want to be able to zip my pants and jacket together, but can't do so if wearing the vest. Pros: Protection. The chest and back protector are top notch. The mesh fabric seems very durable. The foam inserts for added hip protection are a nice touch. The quality is what you would expect from A-Stars - always first rate. And the customer service at RevZilla is unmatched! May 9, 2011
