How did we test? Well, we skied, as much as we could in every weather condition imaginable. We skied in the resorts and in the backcountry of the Tahoe basin. We skied in the frigid cold, warm spring-like days, in sideways snowstorms, and the pouring rain. We tested each ski helmet many times and on multiple heads. We used different goggles with each helmet, put our heads together, and judged each helmet on a scale of 1-10 in each of our testing categories.
