Familiarity: I've used it once or twice and have initial impressions
I used this masked twice in bike rides. Both times it was between 35 and 40 degrees and I did not feel cold at all.
Going down the canyon it was like 38 degrees and on my head and neck just felt like it was 75 degrees.
It's so comfortable and it did not smell weird after using twice.
I highly recommend this balaclava for biking or whatever you do outside in cold weather.
