Familiarity: I've used it several times
I use it on road rides when the temps drop below 40. The material is thick enough, blocks wind well. There is not enough tension around the edges. Wind gets in freely. It turns your ears into cooling fins. it just does not protect the ears enough. I think it would be fine for hiking or mtb rides, just not good for road cycling.
