With the thick gloves, my hands stay absolutely warm and toasty down to the mid 30's. Even with the summer gloves and heated grips, at 45 degrees, it really only my 2 index fingers that get cold (I habitually ride with those on the brake and clutch levers). I have looked at a couple heated options, but the only ones they stock at the local stores were thin textile, they didn't seem like they'd have good protection while I'm riding around on cold wet surfaces. I forgot about mitts, that may be a very viable option, I'll look into those a bit more and check out some of the glove options posted here. Thanks for all the input, I'll have some good options to explore.
