Great for Street. Less than Ideal under 1-piece suit I purchased this mainly for the track as it is required for intermediate and advanced groups. When used under My one piece the shoulder straps bunch up and are unbearable to ride with. What I ended up doing is just detaching the back protector from the front and just running the back protector, thus eliminating the need for the shoulder straps. I use it on the streets as a whole with the chest piece on hot days just over a t-shirt or under a hoody, and it fits comfortable. I have gone down with it both on the street and on the track and it has done its job. The only thing like I said is it not a good design for using under a one piece, for this reason I wish I had not purchased it and can not recommend it. June 29, 2013
Good protection, lightweight and good looks Worn only once, on a trip of 335 miles. I was driving in a warm climate. Felt no discomfort and was easy to wear. My friend put the guard and punched him in the back and he barely felt the impact. That was funny. November 19, 2012
Best product for tight suits or jackets! After much research, multiple purchases and returns, I've found this item to suit my needs perfectly. I needed protection for the back and chest that can fit in my snug 1 piece leathers for track days and under my jackets for street use giving me CE level 2 for back and CE for chest and this item fits the bill! Another quality piece by Alpinestars and Revzilla's great customer service and fast shipping makes me a happy customer every time! June 20, 2012
Great "vest" I love this product. I bought this due to its safety rating. It fits well and doesn't move about under you my jacket. I have a naked bike so sitting up the back protector is short enough that it doesn't hit the seat or anything. Its a great piece of protection. HIghly recommend! April 29, 2011
Great Vest, Exactly what I was trying to find I needed a new vest that would protect me better than my Icon vest but not hinder my movement, especailly on the track. This vest fits the bill. It fits great and feels strong. I hope to never have to reply on its strength but I am confident that it will do the job. As always, great service from Revzilla, shipped fast and tracked the package easily. Thanks! May 25, 2010
Nicely designed protection This is a great product. My jacket already has elbow, shoulder, and back protection like most, but I wanted some extra protection for those vital organs around the chest area. This does the trick nicely with a little adjusting. I will probably take the back protector out of my jacket now since I won't need it with this. I think Alpinestars has made a well designed and comfortable product for that added bit of safety you might like to have. December 14, 2008

A shopper asked: Hi!
If XL bionic back protector fits me nicely, then SMX vest size XL will fit the same?

A shopper asked: Is this product rated for multiple impact protection and re-useable after a crash?

In the product reviews for competing products- ie the Dainese Thorax Wave and ForceField Extreme Flite- you guys explained how the Dainese is a one-crash only product -vs- the ForceField, which is a multiple crash re-useable product.

But, you guys made no such explanations for the Alpinestars SMX-Bionic 2 vest. How does it rate/ compare?

Thanks for your help.

Stevan P: To date Forcefield is the only crash protection that is deemed reusable due to the energy reflection properties. Most other manufacturer's armor is rated for single crash protection due to energy absorption properties. With that said the protection provided by the SMX-Bionic 2 Vest is still highly rated.

A shopper asked: Hello. I'm thinking about buying a protection for motorcycling ride and I in doubt about two models.
SMX BIONIC PROTECTION VEST and TRACK PROTECTION VEST. Can you help me telling the difference between that? With one has a better protection? I understand that the protection for the back is the same, as both of then has Level 2 of protection but what about the chest? Witch one protect more?

Thanks for you help. I's amazing how your videos are good to understand the products!!

Joel P: While the SMX Bionic 2 Protection Vest has a hard chest protector, the Track Protection Vest provides greater surface area coverage for the torso with its multiple impact resistant foam inserts. In my experience, the Track Protection Vest fits better and provides more comfort than the SMX Bionic 2 Protection Vest especially when worn under a street or racing jacket/suit. Aug 16, 2011
