Yeah, back when I didn't have a car and I needed to make a long trip in the cold I would get a thin pair of knit gloves, then put a pair of latex gloves over those, then put on my insulated leather gloves. The latex gloves helped create an air barrier that worked pretty well.
But I was looking for a little more elegant solution. I have an hour drive each morning. I don't mind low 40's, that's what it was today and my hands were cold but it wasn't bad. When it gets down in the 30's it's painful by the time I'm halfway there. When it's in the 20's it's painful after about 5 minutes.
The heated gloves I'm looking at aren't cheap, they do heat down through the fingers. So I imagine that would help, but they are $170 plus another 99 if I want the batteries instead of wiring them into my bike. I'm pretty sure those would do the trick.
I'm not sure about the hippo hands muffs, those seem like they would be awkward. Also the heated grips seem to be operating from the wrong side, I don't know how well that would work for the outside of my hands. I may look at finding a good thermal liner to try first.
I saw one post give the deflector a plus, anyone put them on a 900 custom?
