The D4 Composite helmet is the latest in the legendary Troy Lee Designs Daytona series. The full face helmet’s shell is made from an aerospace-grade fibreglass. The MIPS Brain Protection System in the D4 means the Troy Lee helmet delivers ultimate protection. MIPS is a layer in the helmet that allows the head to slide relative to the helmet, this reduces any rotational movement that would affect the brain. A collarbone suspension system improves safety by directing pressure away from the collarbone in case of any tumbles. As a result, The D4 has the most protective energy system Troy Lee Designs has ever given its riders.
