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
Review of Bionic SP Vest I had originally attempted to purchase the alpinestars track vest due to the padding on the shoulders and kidneys, but there was a mix up and i got this instead. This vest worked out a little better due to its lack of bulk and let me move in my suit; additionally, I think it is really well ventilated. I love how the back protector stays in one place - i have had the shoulder straps and button-in protector for my suit and both were frustrating.My only recommendation would be to provide more Velcro along the waist in order to make it more snug. Thankfully I have not been down while wearing it so I can't report how it crashes! May 3, 2010

RevZilla Store asked: Why did you choose this?
A S: I need some back protection for my old A* SMX jacket. I figured the added chest protection and maximum airflow of this would be a better choice than the floating inserts otherwise available. Jun 19, 2014
Radu B: I want back protection; the back protector wasn't very comfortable and the front velcrow would come apart easily. This vest is much nicer and adds protection to chest and collarbones. I love it. Jun 13, 2014
Eric C: Extra protection and versatility for use with different riding gear. Apr 17, 2014
ANDREW B: Good protection, minimally bulky, lightweight, breathability, can wear under jackets without feeling stiff and ok pricing. Jan 8, 2014

Kan P: Definitely get a Medium. I'm 5'11, 165 pounds, chest size between 39" to 40", it fits very well and it's just a little snug. Perfect size for me. Hopefully this will be good information for those who are planning to get this vest but not sure what size to get. Feb 14, 2013

A shopper asked: I an wondering if this vest can be worn under light clothing without looking like robocop? Also, I am a woman bust size 34, 140lb and 5'4". What size would be a comfortable fit? Thank you. Mar 13, 2012

Bo: IMO it can. It wouldn't look "stupid" but u take away a lot of protection- elbows, shoulders and forearms. Ride as protected as u can bud, just ask someone who had crashed already or watch YT videos with gear crash reviews. But to answer your question, yes, it would fit under a loose t-shirt no problem Mar 26, 2013

RevZilla: You can wear the Alpinestars Bionic SP Vest under a shirt, but it will look a bit bulky. If you are looking for a thinner aspect, we would recommend the Alpinestars Track Protection Vest.
Based on your measurements, we would recommend you a size Small.
