Ski helmets should be plenty warm to keep your head and ears comfortable in high-elevation alpine conditions. If you run cold, we recommend seeking out a helmet known for its warmth, like the Sweet Protection Switcher. You can also layer a thin beanie underneath a well-fitting helmet to add extra oomph if your noggin just won’t warm up.
Also, an adjustable ventilation system will allow you to close your vents to keep precious heat in, like in the Wildhorn Highline.
