Хорошая вещь, защита 2 уровня, мягкая, удобная, но в куртки Dainese не подходит

Breathes well, super flexible, would recommend

These protectors are flexible and soft, even in colder temperatures. I'm using them in a summer jacket though, and so the amount of air that goes through them really helps. I used these in a Revit Matador jacket as a replacement for the stock Revit divided chest protectors. They fit perfectly in the jacket's pockets.

Super cool!

I have not try it in action and i hope i'll never do :) But it feels so nice to have it. I feel there is "something extra" on my chest but not as a burden - more as extra safety. So from this perspective it is absolutely worth of buying it!

Looks great

Fits perfect in a Dainese racing 3 jacket. Hopefully I will never find out how it works in an accident :)
