The Ion 12 totally delivers on the gnarliest of terrain and the longest of days. A combo of durable glass-filled nylon and aluminum produces a lightweight and bulletproof build for efficient uphill travel. The binding also features easily accessible heel lifts and an intuitive toe step-in system to get you from the trailhead to the skin track quickly. Release values ranging from 5 to 12 make it ultra-reliable on the descent, too.
