I can see in NJ it must get damned cold! When the weather got cold in CA or NC I wear a Gerbing Heated Jacket. Works great! Haven't used their gloves has have other responders. But, I've been very comfortable with "Olympia 4350 All Season I Gloves" have, but I just found on the Olympia gloves site for you.
I like them because they are very movement friendly, STOP the wind, and between the heated jacket and on a rare occasion, a glove liner, they get the job done. But the Olympia site gives you a wealth of choices.
I suppose I've been riding in the 40 degree temp range, but, not on purpose. I used to have a 55 degree threshold in California, at my house, but, I never really stopped to consider that when I got up into the Santa Cruz Mountains and on the Pacific Coast it more than likely to be quite a few degrees colder than that, easily getting it down to the lower 40's.
