My body runs so hot that I don't really give a shit unless it's under 0F. Then I have everything cinched closed to prevent frost bite anyway so if no air gets in, no snow gets in. I have long gloves that can easily go way over or under the sleeve cuffs. The have wrist straps and cuff straps to pull them tight.
Regular riding days, when its sunny and over 20 I'm spraying snow at myself with vents open just to get the cool down spray...
