Went out for a long ride this past weekend with an air temperature of ~35 degrees and a steady 10-15mph wind, bringing the perceived temperature down significantly. To say the least I couldn't be happier with this purchase. There is enough play in the fabric to allow it to be pulled over the nose for maximum warmth, then below for a little better breathing and then even lower for maximum air exposure.  Not once, did I think about my ears being cold, or neck being cold, no wind burnt lips either.  Its light enough that you hardly notice it yet some how provides enough breathability and thermal insulation to keep you warm during the entire ride. Would highly recommend to anyone looking for more coverage than just the skull cap. Best yet, its easily rinseable and washable and fits well below a bike helmet.
