If it feels like armour in your bike kit then the law demands it is actually proper, protective armour. Here's how to tell how effective your impact protection is...
Bought the Alpinestars Nucleon KR-2I Back Insert - Black for my new Alpinestars jacket. Great quality and fast shipping. Flexible compared to previous back protectors that I have had.
Excellent service from Customer support. Really superb. Item was received very promptly and once in situ fits well. Only concern is, even though ii is the large version, it could still be several inches longer to provide greater protection for the lower back/spine area
Fits snugly in pocket on jacket, sturdy and didn't notice it was there once I was riding
First class service from sportsbikeshop, as always they keep you updated every step of the way
Excellent service once again from sportsbikeshop. Exactly what I needed in stock and super fast delivery.
Back protector is really comfy in the jacket.
The only downside to it is that it's quite short.. if you needed full back cover I'd probably go for a separate protector.
Was a slightly tight fit getting the size M back protector into my size M Alpinestars jacket but managed after a couple of minutes. Once in you almost never notice it's there unless you press your back against something. Would be ideal if it was a little longer at the bottom to cover more lower spine but for a relatively cheap insert it's great
Lightweight, flexible, really nice fit. I would recommend.
Perfect fit for jacket..nice bit of kit.. usual Sportsbikeshop service...
It fits perfectly into my alpine stars jacket. It doesn't feel noticeable while wearing. It feels solid.
Nice product. Would be good if included with the jacket but never mind. Fits nicely and can hardly be felt once worn
Great fit and the sizing was spot on. As always fast and hassle free delivery from sportsbikeshop.
Fitted into jacket snuggly hopefully mould into shape of back after a couple of ride outs. Really top quality piece of kit.
Excellent bit of kit as always fantastic service from sporstbikeshop
Bought the medium and it fits perfectly in the Andes V3 medium jacket.
Excellent service as usual from SBS
I bought the Alpinestars Nucleon KR-2I Back Insert for my Alpinestars Andes V3 Drystar Textile Jacket as extra protection, it just slots into the compartment in the back of the jacket, a simple installation and fits great. Many thanks again, sportsbikeshop for another great product.
I bought this to slot into my Alpinestars V3 Andes jacket. Now I don't feel guilty for not wearing my full-size Knox back plate if I'm out for a more relaxed ride. A good price too, as always from Sportsbikeshop.
I really wish that these were standard in the jackets, why do the manufacturers value shoulders and elbows over backbones?
Fits the jacket easily (Alpinestars Solano) and feels comfortable - you hardly notice its there.
lightweight but more substantial than the one that came with my ktm jacket. fitted well, don't know you have it on when riding.

Alpinestars recommends a size large insert for your jacket.
According to the compatibility chart you will need the Large protector in this instance.

You will require size Large.
A 2XL jacket requires the large Nucleon back protector.
We would recommend the medium back protector.
This is the Level 2 CE approved back insert that Alpinestars recommend. If you were to purchase an Alpinestars Jacket in a UK size 46, you require the Large insert.
