The Purpose of This is What?

I really don't understand stuff like this. These are fingerless gloves from UGG and the description posted was the following: "slick fingerless gloves feature light insulation for added warmth." Really? I doubt. The whole purpose of gloves to me is to keep my fingers warm.....what are these supposed to do? Somebody clue me in. Thanks. If you want these "palm/wrist warmers" you can get them at Nordstrom for $45 (sheesh! waste of money).
