Fantastic helmet. I have a couple of these and love them. This color just doesn't go with any of my kit. Has some slight discoloratio where the blue/purple is showing through the red. Only noticeable close up. Rarely worn. Extremely comfortable, protective, and lightweight including Smith’s most advanced MIPS and Koroyd technologies. Smith Quantum helmet is highly rated by Outdoor Gear Lab (https://www.outdoorgearlab.com/reviews/snow-sports/ski-helmet/smith-quantum-mips). Size: Large Color: Matte Red The Quantum is protection with maximum horsepower. Using Koroyd and Smith’s innovative Exoskeleton design to provide increased protection, this is the helmet for athletes pushing the limits on the mountain. ADVANCED IMPACT TECHNOLOGY Koroyd’s welded tubes crumple instantly and consistently on impact, absorbing maximum force in a controlled manner, minimizing energy transferred to your head. DIRECT AND ANGLED IMPACT PROTECTION This unique behavior helps to protect your skull and brain from direct and angled impacts which may reduce the risk of suffering a life-changing injury. ADVANCED BREATHABILITY AND COOLING Air flows consistently through the open cells so hot air from your head can easily escape, ensuring more efficient cooling in the most intense conditions. PROTECTION NEVER FELT SO LIGHT Koroyd features the world’s thinnest walled tubes, resulting in a structure which is 95% air. This reduces weight and enhances comfort without compromising on safety.
