So I ride all year, in NH. It get's cold, really cold. So cold, I've killed the battery many times trying to wake up the bike(hello kick starter).
Keeping warm has become a science, which I have mastered for the most part.
I bought battery powered gloves and heated insoles(wired to the bike) last winter, which worked great. The only problem with the gloves was the battery sits up on top of the wrist, in the wind. Freezing the batteries shortens how long they will run. I needed a way to get them out of the wind....

Well, this summer at work, some Bar Mitt samples showed up. In the box was a set for motorcycles/ATV! As the only nut at work still invested in riding all year, I was given first dibs. You don't need to ask me twice!

First stab at putting them on, I realized my Barkbuster Storm palstic might be a problem because the Bar Mitt opening on the bar side wasn't anywhere close to being big enough. What I ended up doing was unbolting the Barkbuster at the bar end, pushing it close to the bar, and sliding/stretching the mitt over. The other problem was no hole for the mirrors...popped a hole through the neoprene and took care of that.

Got them on in time for a 34º F morning. Decided to put them to the test and just ride with my leather road gloves. Wow! Warm hands! Then got to try them in the rain. Wow! Warm and mostly dry leather gloves!

The down side - when you take your hands out at speed, the opening closes and flaps around. This could be a problem in an emergency situation. My solution for this, add some electrical wire into the seam on the opening. Oh yeah, they are ugly, but function trumps form in this case.

If you ride in cooler weather you might enjoy them instead of using big, bulky gloves. I'm hoping that my heated gloves will keep more than warm on those 10º mornings, seems likely.

 

I had the Ski-Doo version of them on my sled. For some reason my hands can't take cold weather at all, and that can make snowmobiling unfun, but with the gauntlets on, I was good to go. Mine were good for putting on/taking off, because they were velcro the whole way down the side that faces back toward the rider. I just carried them in my tail bag for when I needed them. Now that I've sold the sled, they have another use....

 

Reminds me of the Vetter Hippo Hands that used to be around back in the Windjammer fairing days. They had insulation with fleece exposed on the inside. They really worked. Those look quite similar. I think Craig Vetter had some kind of stiffening agent at the opening to help hand reentry, but quite similar otherwise. Good tools for the job.

 

Rooster's look way warmer and drier than mine. The Bar Mitts are only neoprene, not even thick enough to use as a wet suit here in summer. But they do help block the wind/weather at speed.
I may need to find that old 80's green wetsuit and glue on another layer before winter is over.

@Rooster - What are your studs? Looks like machine screws. Do you ever ride those on the road?

 

I had the same problem with the opening when I had them on the sled, but in the bike it wasn't an issue, because my hand guards are bigger and they keep the opening wider.

The studs are Super Trac Ice Racing studs. 1/2" long. Same company as these:

Never tried them on the road, but I don't think they would work, or last too well. I won't even ride on my driveway with them.

 

Its amazing how much warmer your hands can be simply by just reducing the amount of wind/airflow over them.

Couple of years back I creamed a deer with the jeep I had at the time head on at about 60mph. trashed the whole front end sheetmetal and blew the radiator. For the 2 weeks or so it was in the shop I had to ride the KLX as it was the only transportation I had back and forth to work in late November early December. In MO this really wasn't a huge deal if you dress for it but my hands were always cold. Couple of cut off gallon milk jugs zip tied to the bars and I was back on the road and MUCH warmer.

 

this is what people on the club are using for those cold days
