Most comfortable level 1 protection!(09.02.2025)
Anonymous293157930
The important thing to know is this is level 1 and not 2, for me that is good enough for chest (for back I went level 2) . They appear to be good quality, and don't interfere with movement when in the jacket. It is easy to forget they are there. Why not add them if a jacket accommodates them? It is best to fill in the empty front pockets with what currently is their latest protection technology. Thanks FC-Moto!
