Rohloff twist shifter is too slippery when sweating My Rohloff Speedhub is pretty slick, but unfortunately so is the twist shifter when I'm sweaty.  In southern Florida, riding my trike, that's pretty much all the time.  Switching gears already has higher resistance than your standard derailleur; when under a bit of load it takes even more effort, and there are times when I literally cannot shift gears because my grip slips.  I don't have many options to change out the shifter (it's custom to Rohloff) and it's irregularly shaped so I don't think I could use bike tape or anything on it.  I'm hoping someone can give me a solution that will give me a good grip even when sweaty or wet that isn't going to look ridiculous or be unwieldy.
Cycling gloves are designed for comfort and to improve grip by absorbing sweat and providing a contact material that provides grip even when damp or wet.  Typically, hands do not sweat much so most cycling gloves will help in this regards.
