Rui Paixão - 01/02/2023

Product as described. Lightweight, quite rigid but moldable to the body, after wearing the jacket with body heat, it only takes a few seconds for it to adapt to the back and become imperceptible.

Alpinestars nucleon kr-2i

David Vieira - 07/05/2020

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

Miguel DB - 04/04/2020

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

Terence - 02/03/2020

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.

Good
