Helmet cover
Currently, I'm wearing a medium thickness fleece balaclava under a ventilated helmet. This morning, I felt the cold on my bald head (under the balaclava of course), especially on downhill runouts where I can be travelling up to 45km/h. I'm thinking of getting a helmet cover which will virtually eliminate wind through the helmet vents but also will cause my head to heat up more so maybe I'll wear a thinner balaclava and a buff or similar setup.
Does anyone else wear a helmet cover at this time of year and how do they like it?
