Just like the Stella Octane one-piece suit, the Stella two-piece suit has the same features but with a tough YKK zipper in the middle to allow for easier entry into full leather coverage. Hard armor and GP protectors minimize impacts in case of a fall. Now, Alpinestars knows that you are not just going to be a passenger on the back, but they know your going to get out and ride you own bike. Sport knee sliders are there so you ride past the guys and show them who’s boss after you take an inside line with your knee down at the track. Put the jacket on then put the pants on with out the wiggling involved in a one-piece suit and ride away.
