Buy a good pair of motorcycle gloves, latex gloves will actually make your hands colder. Gloves made for cycles, snowmobiles etc. are made to be able to use controls and still provide warm and dry. Cost a bit more but worth it.
Haven't tried that -- but latex gloves almost always make my hands sweat.
In the 36-degree morning commutes last April, I wore a thin pair of winter gloves inside a larger pair of heavier/thicker winter gloves. Neither pair worn on their own was 100% great at stopping wind penetration to my fingers, but combined together my hands were comfy-to-warm the whole ride. (These were dry rides, so I didn't have to worry about rain/wet.)
How about one that plugs into the bike's battery!If you want to really go all out on Amazon they have Heated Gloves made for riding.
The ski gloves I've tried are bulkier than I like. I use them when it's really cold, but it's a lot harder to do things like change my headlight setting, changing the motor's power level, etc. The not breathing part of a latex layer is kind of the point, and notionally it could help maintain hand heat (same idea as a vapor barrier) as long as there was another layer over them to prevent convective cooling. If it gets to "sloshy," that I wouldn't like.What about a good pair of ski gloves? Latex doesn't breathe.
Its a pair of thin gloves by 66 Degrees North, bought in Iceland -- I think it is called "Vik" glove -- but I see on their website they offer 3 varieties of that, including one listed as windproof-- I do not recall which specific version of "Vik" I bought while over there.What thin gloves are you using as the liner?
