These imitation fur earbags are nice and warm. I also have the standard earbags: those are slightly less warm, but take up even less space when not in use. So I use the standard version when it's not too cold outside and these imitation fur ones on colder days. I love the concept of earbags and wish I had found them years ago. They are easy to use and super convenient to carry around. I just put them in the pocket of my jacket when not in use, instead of having big earmuffs taking up space in a bag.
