Troy Lee Designs D4 Carbon Full Face MTB Helmet
The D4 Carbon helmet is the latest in the legendary Troy Lee Designs Daytona series. The D4 Carbon builds on the success of the best full face helmets ever to be the most advanced downhill, freeride, and BMX helmet going. It is sure to continue the legend and pro success of Troy Lee Designs D3 and is the go-to for anyone seeking the very best.
The D4 Carbon helmet has a TeXtreme carbon fibre shell. The carbon has a spread tow construction that uses straighter fibres than standard carbon fibre. This results in a thinner laminate that reduces weight while achieving a greater rigidness, increased strength, and improved impact tolerance.
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 full face mtb 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.

Troy Lee Designs D4 Helmet Size Guide
How to measure
To find the circumference of your head, place a tape measure in the centre of your forehead, wrap it around above your ears and around the back of your head. If there's a slight difference between two different sizes, always go for the tighter size.
