I haven't had the opportunity to wear it on a bike ride just yet but the item fits great.  It seems like it would give a good amount of warmth when I ride it.  For now I will give it 5 stars and once I ride with it, i will give it an updated review.

So I have used this on multiple rides and even when I am not on a bike.  It is perfect for winter riding and just keeping your face and neck warm on those ole so cold days.  The fit is indeed perfect.  I can get a great fit with hair on my head and even if my head is bald.
You can also easily pull the mouth part below your jawline if the heat gets a little too much.

The only issue I can find, and I really have to make it a issue. Is that it is not an great fit i your wear glasses.  It because of the way it is positioned on your face it can cause your breath to raise right into my glasses and cause the glasses to fog up a bit.  Though this only really happens on days when the temperature is below 25 For so.

I would recommend this item for anyone who wants a great fitting and warming head covering.
