Usually right after my helmet comes off, I take off my chest protector. Yet I found myself not removing this Thor chest protector. Then I began paying some attention to the Force protector, including how well it fit and how it didn't rub anything too much. Its comfort seems rooted in its so-called triple-layer back-protection system. It's made up of a thick, rubbery foam along the center of the back plate that keeps the Thor chest protector riding high and away from your back or neck.
