safety Marker developed a new type of foam that’s immune to temperature changes (many foams firm up in cold) and boosts shock absorption. The result (according to the company’s third-party testing): 22 percent more impact protection than with standard foam. Bonus: This new material has immediate rebound, so you’ll be better protected if you hit your head multiple times in a fall. Gripe: Some testers found it bulky.
Ventilation A series of vents work with your goggles (any model) to pull moist air through channels built into the helmet, and out the back via corresponding vents.
