EPS Liners: If it wasn't the best, we wouldn't use it. But 15 years of R&D experience and thousands of impact tests prove that EPS (expanded polystyrene is truly the best material for snowsport helmet liners. Why? Because EPS offers the most consistent performance over the widest range of conditions; gram for gram it absorbs more impact energy than other materials; and it's incredibly light. No other material offers all three benefits together, and nobody has more experience to prove it. Goggle Notch: Every one of our helmets is designed to match-up with goggles for a comfortable,
