Another option is
ReGrip. These fit over your existing grip, do not retain water and work fine with heated grips. I have used them on a few bikes. You need the yellow/Medium size. You just slide them over the grips, then pull the inner strip out until you have coverage, then trim with a razor knife. They are much longer than needed. I first used these for wheelbarrow handles, liked them and tried them on motorcycles. Inexpensive if you hate them too.
FWIW, I've also had Grip Puppies and Grip Buddies in the past and liked them too, the ReGrip is just a solid generic solution instead of a higher priced moto specific solution. You can sometimes find this local at places like ACE hardware and Home Depot/Lowes too.
