Going to sound like my mother now, but we had some of these and found that we couldn't hear a thing with them on - so we banned them on the yard cos this was so dangerous.
I use one of those wooly tube things, I think it's called a snood, which I wear round my neck, but can pull up over the top of my hat and round the lower part of my face when it's as cold as it is now!
silk scarf wrapped round the head ears and neck works well apparently although im yet to try it. because its so thin it wont hurt your head to have it on under your hat.
