Snell RS-98 is a voluntary certification that goes beyond the mandatory safety standards (like CE EN1077 or ASTM F2040). Helmets with this rating undergo tougher testing — they have to withstand higher impact forces and pass more impact tests than what's legally required. Think of it as the difference between passing the test and acing it.
You'll mostly find Snell RS-98 on racing helmets and premium models built for maximum protection. If you're charging hard, racing, or skiing at high speeds where impacts can be more severe, that extra level of protection is a smart investment.
For most recreational skiers and riders, a helmet that meets CE EN1077 or ASTM F2040 provides solid protection for typical resort skiing. But if safety is your top priority and you don't mind spending a bit more, Snell RS-98 gives you that extra margin of confidence.
