Putting on a full 1-piece suit usually means you will be roasting hot by the end of the ride. Alpinestars has perforated the RC-1 suit to allow more airflow, and they have built the interior with a removable liner to ease entry and exit. Just like their no-compromise race suits, the aerodynamic hump helps for extra speed down the straight and keeps your head from smacking the ground too hard should you land on your back. Hard armor in the shoulders and elbows helps reduce any impact on the ground. We all know that any race suit has to have knee sliders, Alpinestars has them with the appropriate GP armor behind the leather. Look good in a full grain leather suit while burning up the local track or out riding on the street in the RC-1 suit from Alpinestars.
