Scott’s Split: cutting-edge aerodynamics for your leading edge. Scott’s Split takes aerodynamics to the next level so your PRs don't stand a chance. Extensive lab-based and on-road testing results in a snubbed teardrop shape that smooths “dirty air” whether you have your head down or eyes up. Clever ventilation channels air through the faceport, along deep internal channels and out a rear exhaust port. This results in a helmet that keeps you cool, even while the competition is starting to heat up. Scott's fully adjustable MRAS fit system provides unmatched comfort as well. The next time you need an edge in a race against the clock, make sure you're in the Split.
