I ordered these a few days ago, and received them today:

I don't like the padding on the palms, so I'll return them.
I just ordered these today:

They don't have a lot of feedback on Amazon, but they look like they're very similar to these:

which have a good amount of feedback.
Notice that they have no padding.
I should have been looking for that all along.
Also notice that they are mostly polyester.
I don't usually associate polyester with being good at wicking away moisture, but there are many types of polyester, and these gloves are made of the right type.
I'll report my findings when these arrive at my house, but I think I've found a winner.
