A great way to enjoy the lower half of Full Face without the crazy steep top. If you ride Half Shell to connect to Full Face, you cut out the Double Diamond riding; however, the bottom still has a few challenges and would probably be a soft Black Diamond. Check it out, you will not regret riding it.
