These grips are 100% silicone and a great way to reduce shock and vibration to your hands.  They are great for adventure bikes and daily commuter bikes, because they grip fantastically with bare hands.  They don't get affected by sweat or water, and always remain perfectly grippy.  There is a thinner one for the throttle side, which makes the grips both around 34 mm in the end use.
