I saw some motorsports mittens in the cabelas magazine. I'm still riding and it's really only my hands that get cold. I looked into the battery operated gloves but they don't really fit the budget. My question, is it OK to ride with mittens, they wuld stay warmer especially with a hand warmer in it? Do they hinder the ability to get to the brake/clutch? I don't have any mittens laying around to test it out.
