I use a product called Chamois Butt'r It is designed for your Butt and works quite well it also works on the hands also .It makes them feel a little slippery but once the gloves are on you don't notice it .I buy it at a pedal bike shop. It really does work very well and only $20 for the big jar and it lasts a long time.
