Alpinestars Nucleon KR-Celli Back Protector Insert - Transparent Smoke

Light , fits jacket well , you don’t know it’s there. Excellent

Purchased to compliment my Alpinestars proton jacket. Fits perfectly and blends in without feeling bulky.

This fits perfectly in my new jacket and you don’t know it’s there. Feels comfy so far. Very happy with it

Fits nicely into my Alpinestars jacket

Fits perfectly in my new leather jacket

Does exactly what it says on the tin ?

A must have for anyone who has a slot for this armour in their jacket.

This Level 1 protector is flexible, lightweight and undetectable in use. It fitted neatly into the pocket on a Berik textile jacket. Recommended.

Very pleased with this. Bought it to go in my new Alpinestars jacket and it’s so slim and flexible you hardly know it’s there.

I bought this to replace the thin foam protector that came in my Alpinestars Stella leather jacket. It was difficult to get the correct size to fit in the pocket and not move around. I ended up with a Medium for a women's size 10 (Euro 44) jacket. Not a perfect fit, as a different shape to the pocket but stays in place. Comfortable and not too bulky.

Fits perfectly in a large andies 3 jacket the soft fabric covered side that’s against your back makes a difference from other back protectors I’ve tried. Very comfortable

The back protector arrived well packaged. It met the description entirely. it slipped into the jacket without problems. no issues at all with ordering process. Easy and straight forward.

Brilliant quality back protector compared with other nucleon types.

Lightweight and comfortable in my Andes v3

Much lighter than earlier versions and a good fit for my Alpinestars Andes jacket. It comes in different sizesso ensure you measure first. Can barely feel it. Can't really argue at the price, after all what price safety.
