Try using a product called Udder Balm. It comes in a square, green can and most pharmacies carry it in the skin care (not the beauty) section. Veterinarians swear by the stuff because it's the only thing that seems to help keep their hands from cracking and drying out no matter what they're doing to their hands. I use Udder Balm when I'm going to be riding in hot or steamy weather and it really works. It's like pure lanolin and while it's a tad gooey it isn't as icky as vaseline can be.
