Alpinestars Nucleon KR-Celli Back Protector Insert - Transparent Smoke

Great product, good price.

Top quality service from Sportsbikeshop as always! .

I bought a Large back protector to fit an XL jacket. Fitted perfectly.

Very light and comfortable, dont know it's there, great quality from alpine stars and excellent service from sbs

Good fit into Alpinestars jacket and more comfortable than any previously used

Barely even know it's there, it's so light and flexible. What more could you ask for. Fitted in my Alpinestars SP-1 V2 leather jacket.

Fits perfect in my new Bogota pro Jacket,

Bought this for my new Alpinestars Andes jacket, its super light and the fit is perfect, you forget its even there.

Bought this to replace the Alpinestars Nucleon KR-1 Celli Back Protector Insert - Black / Red - L as that one (although it was a level 2) was much too stiff. It was like having a wooden board in the back of the jacket and nothing like my more flexible D30 level 2 in my leathers.
This one is a lot better. So much lighter and hardly noticeable and suits the Alpinestars Andes V3 Drystar Textile Jacket a lot more.
Great help and return system/process from Sportsbikeshop.

Staff at Reading recommend this back protector and have found it very comfortable, you don't even know it's there, hope not to test it out but Alpine stars quality is worth it.

Nice lightweight back insert I purchased for the alpine stars hoodie fits in no problem.

Value for money 10/10
Comfort 10/10
Weight 10/10
Fittment 10/10

Very happy with product, I use this in my Alpinestars Sektor Jacket a perfect partnership for light Town and slow speed riding...

Same as always, another great Alpinestars product. Was a little unsure of the sizing, but Sportsbikeshop shop was so helpful with this.
Super finish and fits in my jacket nicely, really comfy in it too. Keeps air moving through jacket in the heat when Riding also.
Thanks to Sportsbikeshop for super fast delivery, great pricing and assistance!!!

Usual alpinestars quality fits jacket well almost unnoticeable.

Very light and sturdy yet flexible. Fits perfectly in my Alpinestars mesh jacket - invisible from the outside and barely noticeable on the inside when worn (indoors currently !)

Is what it is. Good

It was excellent for the few seconds I had it between opening the box and ramming it into my Dainese jacket. What I want in a back protector is invisibility. I don't want to see it, smell it, feel it or even know it's there. This product ticks all of those boxes.
