Anyone tried using handguards/brush guards as an aid to keeping your hands warmer in winter? I bought a cheap pair off Amazon last winter and they definitely help a little bit in reducing windchill. I crashed and broke one last year and the difference between my two hands while riding home with one side fitted has convinced me that they're worthwhile. The cheap ones I have aren't very strong so are pretty useless for protecting from impacts but they do deflect the wind so are particularly useful if (like me) you hate wearing bulky winter gloves.
