I tried the
PI headband and was not satisfied. Too much air got through to my ears and it did not keep them warm enough. Took them back and got an
Endura head band for a couple of dollars more. That was exactly what I was looking for. Keeps the forehead head and ears warm and keeps the wind out of the ears. The top of the head so far has not been getting too cold. For the face, I am using a thin knock off multi tube. As it is getting colder in the mornings and on the ride home, think I will need a bit of a thicker multi tube.
I am very happy with the Endura head band. Thinking of maybe also some of the flaps added to the helmet as some have pointed to before, for when the temps drop more.
