Like many that have already posted, my ears bother me in cooler weather too. I went a different route and bought a slightly larger size Bell helmet (21.75"-24" size) so I could wear my winter hats or earbands. It works! It also has less vents than my original helmet. My Giro helmet couldn't adjust big enough for the thinnest wool hats or ear bands without giving me a headache. Now I'm happy. Love the other suggestions too.
