Super back protector Alpinestars


Super item for back protection. Great cost for perfect product.

Fits perfectly


Buy it to complement the back safety

Good product


Very good quality!!! I feel more safety with Alpinestars back protection and is soft and comfortable to correct size for my jacket!!! Thanks...

Great back protector


As always, a great back protector from Alpinestars

A brand a guarantee!


Nothing to say, AlpineStars is a guarantee! Purchased for AlpineStars jackets (winter and summer) to be moved according to the jacket to be worn.

Alpinestars nucleon kr-2i


Compatible with the Dainese TEmpest 2 D Dry jacket despite, in my expectations, covering the back more in length. The protection is soft and very comfortable

Good protection


Buy it to complement the back safety of an alpinestars Andes V2 Drystar jacket. It is a bit heavy and quite stiff, but I think it will perfectly fulfill its mission in the event of an accident.

Comfortable and discreet


Fits perfectly into the required location inside the jacket to protect the upper back. Does not take up space, does not interfere, lets itself be forgotten. I recommend.



For your jackets.



ventilation and weight.
