For the longest time, I resisted the balaclava and handlebar muffs; they look dorky. This winter I picked up a pair of each. I must be growing up or something because I got me excited to show them both off to a few friends. They both work great! I can't believe how many times I've frozen my ass off for completely stupid reasons. My hands don't get cold until I get off the bike and take my gloves off. An absolute must-have. I will never not have a pair of these on a motorcycle I'm riding in the winter.
here's a link to the muffs I bought. They're made out of neoprene.
