I would guess that this is as slick as the factory cover. If you want a true no slip cover the seat concepts with the gripper top is most likely your best option. Yes, its the more expensive option but very worth the money asked. I have done the SC kit on both of my bikes and i have zero regrets, truly transformed the comfort and the gripper top is fantastic.
I would check this thread by placerload and see what he is asking for the ones he has for sale.
