Alpinestars Bio Armor Back Protector 4.7 5 113 113
Protection that should be in every Alpinestars jacket I bought this back protector to replace the flimsy foam pad that came in my Alpinestars jacket. It just feels safer and flexes a good amount. I can't feel it back there too much but I know it's doing it's job. Make sure you pick one up when you buy your jacket or you'll be ordering it later. April 8, 2014
Very nice With this product on your alpinestars jacket its a great add-on, you will feel right away the level of protection! April 7, 2014
This it bang for the bucks ! Its just value for your money. No complains. I will recommend it for anyone that is looking for a back protector. April 1, 2014
bang for the buck A+ Great product, you won't even know it's there. Served two purposes for me, not only adding protection but recently I lost a bit of weight and my jacket was fitting a bit lose but all sorted now. March 27, 2014
Great protection for the price The small size of this armor fits my Dainese Air Frame euro 44 perfectly. Forget the Dainese back protector, this serves the same function and it fits also. I like how it molds to the curve of your back. After awhile of riding I forgot it was there. Best bang for the buck back protector out there. March 26, 2014
Lightweight,compact and good price. I have a Dainese D-Dry jacket that did not come with a back protector installed and the compartment has a fairly small opening. The medium sized Bio Armor protector was a perfect fit and breaths well. The light weight is a big plus too.I don't really notice it's there. Also, the price just couldn't be beat. March 5, 2014
hmm Bought this in a medium for a size 54 Astars jacket. Should of went with a large. I think one of the review below confused me about it. Other then that its a great insert for a great price. Any Astars Jacket 52+ can fit the LARGE. February 27, 2014
A big upgrade from stock! Threw this in my Alpinestars Viper Air Jacket and it feels WAY better than the foam rubbish that came with the jacket. Highly recommend it! February 12, 2014

A shopper asked: Is this back protector to be used with or without the factory perforated foam piece? May 18, 2011
Answer this · Send to friends Good question? Yes (0) No (0)
alutz187: I guess if the foam piece AND the SAS Tec piece both fit in your slot in your jacket it's probably not a horrible idea to use both. I would think this would get really uncomfortable and would restrict air flow. The sas tec armor manufactured and tested to withstand the hardest impacts by itself, so it's not necessary to use both. Also, the sas tec piece is much more flexible and body conforming then the foam, so the foam might restrict you from getting the full perks of having this armor. May 23, 2011

forzaArmata: Thanks for the replies everybody.

However...
Upon inserting this back protector into my Tech 1-R jacket, I realized that it flops around unless the factory foam piece is in there with it. It adds a little more bulk, but it is totally manageable. It just doesn't feel right on its own.

Thanks.

Tim88: I just put mine in outside the foam i.e. foam closer to my back, for a bit of added comfort and protection. It still fits snugly, and bulks the jacket out a bit too. I doubt leaving the foam in or out will make much difference if you prang Dec 5, 2011
Reply to Tim88 Good answer? Yes (0) No (0)
Clevermeat: I guess it really depends on the type of jacket you've got and how thick the foam piece is and how much room you've got. I tried doing just that with my Shift jacket and both of them just wouldn't fit inside the sleeve for the armor. Nov 28, 2011

A shopper asked: I have the Alpinestars Women's Stella Sigma Drystar Jacket in a size med and I am wondering if the Alpinestars Bio Armor Back Protector will fit into the jacket and if so what size? also this is a hard shell correct??? Sep 18, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Tyler D: This back protector isn't really a "hard shell" it is a high density rubber material much like your shoulder and elbow pads most likely are. The material will flex and mold to you body once warmed. The best way to know what size you need is to measure the height of the pocket in your jacket. There is typically a foam insert in there already so that may be measured if you wish. there is then a sizing chart:

Small 14.5" Height
9.75" Widest Point
6.5" Narrowest Point

Medium 16.25" Height
9.5" Widest Point
6.75" Narrowest Point

Large 18.5" Height
10" Widest Point
6.75" Narrowest Point

The piece could also be trimmed due to the material but I would not suggest that. I own one and love it.

Joann H: I have the AStars Anouke leather jacket in a size 10 with the Bio Armor back protector that Revzilla recommended and selected the size for it.
It fits very well and is comfortable because it its horizontal segmentation. This is a stiff and substantial armor, but it is not hard shell. It is much beefier than the thin foam pad that came with the jacket, though. A good upgrade.

Michael G: It is not hard shell. The protector is all the same material. If you were to hit the protector when on a table, the material feels like the density of clay. The density is not like foam Sep 18, 2013

Joann H: Sorry, I have no idea.
Sounds like two back protectors in one back protector pocket would be very cumbersome and immobilizing. Might be hard on the pocket fabric too where it wears.
I use the bio armor protector and it seems ideal?more protection and better fitting than the stock Astars back pad.

Call Rev and talk to them. Small might be too small and maybe medium is best but they sould answer that.

Joann H: I'm not familiar with that specific model jacket, but I do have 3 AStars jackets, all size 46. When I upgraded the back armor, tha folks at Revzilla sent me what they thought would fit. And it did. I think it was a Small, but not absolutely sure. I'd call and ask them. Exchange is easy too.
You replace the original foam pad with the bio armor, not use them both. The bio armor is a nice upgrade and is very comfortable to wear. It flexes with you and ventilates well enough.

A s: It fits well and has more support than the jacket accompanied foam comfort padding. It seems a bit small for the size jacket, not sure if I would recommend purchasing a size up as I do not know if it would fit the jacket and be too large and cumbersome to be effective and comfortable.

A shopper asked: The SMK is an older A* jacket, but I was hoping this would fit it, as I do not want to get the older RC back protector. As well, would the A* Bionic chest pad fit in the SMK?

Thanks,
Ben

RevZilla: Since the SMK is an older jacket, we do not have one here to measure. If you measure the length and width of the back protector pocket on your jacket, you can compare it to the measurements for the Bio Armor provided on the Size Chart and see if they line up. Aug 17, 2012

A shopper asked: I recently bought Alpinestar's Vika leather jacket, which has zero back armor. Would this work with the jacket? I'm unsure if the jacket has a 'slot' for the armor or not so, yeah. Mar 1, 2014
