The Japanese company Iomic has seen much success in recent years since the mainstream acceptance of Ion power. Ion power when used in the golf grip improves blood flow through the hand and entire arm. Iomic grips contain the highest concentrate of healing ion power at 500+ per cubic centimeter. Wet weather or perspiration doesn't penetrate the grip and its soft feel absorbs vibration.  The grips are made of advance ceramics and polymers. Making them not only waterproof, but crack proof and impressively comfortable. The Iomic putter grip is a tested shape and material that is water proof and provides a very natural feeling in your hands. The exciting colors give your putter a special look from what may be considered not so common in the golf grip world.
