Alpinestars Back Protector

07 June 2025 by Anonymous

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.

Great back protector when you find the right size.

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.

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.

Got your back

The Alpine Stars back protectors come in a range of sizes, so its easy to find the perfect fit for your jacket.
The construction quality is really good, as you would expect, and the protection rating is ideal for road use.
Despite the thickness of the padding, it remains very comfortable. Even on the longest rides you hardly notice it.
All jackets should come with this level of protection as standard.

Better Fit

26 April 2022 by Chris G

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.
