I tried thin Nitrile gloves. They are like surgical gloves, but in nitrile rather than latex, which makes them more resistant to oils and solvents. They are great when you need to soak your hands in oil, but otherwise they are sweaty and they tend to get pinched under the tire when you remount it.

Now I use thin cotton gloves that have their inside dipped in rubber. They are not as sticky and breathe a bit more, so it's easy to mount and dismount a tire with them. I carry them with my tube patches, so I always have them for the dirty work.
