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 D4 Composite brings the same badass looks, protection, and expertise as the D4 Carbon with only a minor weight penalty.
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. The new downhill, freeride, and BMX helmet is certified to CPSC 1203, CE EN1078, ASTM F1952 (DH), and ASTM 2032 (BMX) safety standards.
Top protection, badass looks, and a pedigree that no one can touch. The D4 is set to continue Troy Lee Design’s legacy for years to come.
