I picked up one of these and while back and have been really surprised at how warm it actually is. And you can see in the picture there they have the bottom rolled up but you can unroll it and it should easily cover most peoples ears. I don't have it with me at the moment but if you want I could post a picture of it unrolled, it's pretty long. Amazon lists it as 2.4oz but tbh I haven't actually weighed mine to verify that.
