I swear by the handlebar mits, I'm sure most of you that are in China will know what I am referring to. Those over-mits that are applied over the bar ends that make an appearance in the cold areas of China at this time of year.

I have several pairs, with a couple of extra pairs I bought at a "everything" motorcycle wholesale store in QianDaoHu town. The ones I purchased from there are slightly bigger than the norm, and are fairly well constructed. I liked them so much that a few months ago when I was riding down that way with mates, we stopped at the store and everyone bought a pair. Some bought several pairs (me included) along with a few other items. The store is great, full of all things motorcycle related, but not motorcycles. Lights, HID lights, crash bars, inner tubes, helmets (though not high end brands), visors, seasonal riding gear, spark plugs, all the little hard to find items. The handle bar mits are cosy in the coldest part of winter and I swear by them. I'll get a couple of photos and post them here so that one can see the brand etc. On the Jetmax there is a flow of warm air that radiates upwards via the handle bar plastics, and exits right by each hand grip. When combined with the handle bar mits, I could get away with not wearing any gloves at all during snowfall or rainfall and winter, however as I try to be a ATGATT type rider, I wear gloves, sometimes fingerless leather gloves but most of the time, it's full leather regular gloves. I don't like the bulky feel or lack of feel from typical winter gloves so the handle bar mits are a great solution.
I have found the handle bar mits just as great on my Dragstar Classic even though it has exposed handle bars etc.
