Consider Joe Rocket Windchill gloves.
Real leather, so wind doesn't leak through like textile. They've proven to be actually waterproof as well. A wet leather glove is what it is, but my hands have never been wet.
With Oxford heated grips ( won't own a bike without em) I ride down in to the teens in perfect comfort. Now, I'm not claiming my hands are as warm as sitting on the couch by the fire, but I never think about my hands being cold. There's no form of wind protection on my bike. I happily ditched the hippo hands after finding these gloves.
My previous gloves were BMW Pro Winters and they just sucked. Impossible to get them to jive with myacket sleeve and the wind shot right through the textile once I hit higher speeds.
The Joe Rockets have a very generous cuff that's easy to fit over your sleeves. A strong precurve and thinner palm makes them not feel like a bulky, winter glove at all. I think I paid $65 for them.
Whatever you get I would really consider getting something leather. The wind barrier is the most important thing to keep the cold out and your body heat in. I've yet to find a textile glove that doesn't let air through on the highway. I've got much bulkier, heavily insulated textile snowmobile gloves , but they just don't cut it on the highway. They do fine tooling around in the woods on a dirt bike.
Edit: oh yeah, and the Joe Rockets have a legit left-hand visor squeegee!
