I'm pretty dialed in with the cold weather clothing. No problems with hands, feet, torso.
But - I'm noticing this year that my EYES feel like they are freezing. I wear regular cycling glasses.
Any suggestions? Do they make fleece eyeball warmers? :-)
In a word: Goggles. You could buy ski or snowmobile goggles, but they are pricey and are tinted too dark. I bought these for $8 and I wear them when the temps get below 20*, or if it's very windy. Try to find a pair that seal well against your face. This is important to prevent your warm moist exhale from fogging the inside of the lenses.
