Last year I wore a simple pair of fleece gloves over my riding gloves.
I was very satisfied with the set up. I had the padding and the glove I like and soft fleece to be gentle on the nose and to keep me warm until I got so toasty I had to take them off.
About a month ago I found a pair of 180's convertible gloves at Sports Authority, left over from last year, 40% off clearance. I paid @ $9.
They're soft gloves with little grippy o's on the fingers. They have a windstop mitten like cover for the fingers and there's gripp things on that too.
As I rode around the reservoir today I really got to appreciate these gloves and would grab another two or three pair if I could. My regular cycling gloves fit snug underneath, the grip was more than adequate, the fleece patch on the back was much appreciated by my nose, and I loved the convertibility of the windstop cover that I could put one a few or all of my fingers under. I played around with a bunch of options and all were just great.
They also saved me from getting into trouble for signaling back at the idiot who let out a high pitched whistle as he passed.
The only single digit available was my thumb, so I gave him that. He couldn't hear my words though...
The closest I can come to it is:

Anyway, I find winter cycling gloves to be too specific and never ideal. They're too warm or not warm enough, overly bulky or not properly padded. I recommend trying fleece gloves over your regular cycling gloves and see how it works out.
