After many years of searching, I finally found a new motorcycle jacket which meets my requirements. Unfortunately, because of my requirements (leather, black, waterproof, long, classic cut) I don’t have soooo the wide selection was already a challenge. The new jacket fits well, only with my usual bust back protector to strap it something collided. That leads me to the question… ..there is a difference in terms of mental safety between a L evel II back protector for strap-on or a level II protector element, which is housed in the jacket? Note: I already googled, but often apples are compared with pears in the search results like the foam cloth, which is stuck in many jackets when delivered and high-end strap-on protectors. I know the difference according to a par involuntary spontaneous stops without getting off from my own perspective.
