Troy Lee Designs D4 Polyacrylite Helmet - The Line in Charcoal/White

Season:2026

Brand:Troy Lee Designs

Code:TLD174TheLine-CHAWHT

The reigning king of full-face helmets, the D4 range expands with a Polyacrylite model packing the same safety and comfort features as the premium carbon and composite models into a price-conscious shell. Details make the D4 the most coveted full-face in mountain biking, including Mips® C2 brain protection, an air intake system for ventilation, and an unmatched anatomical fit.

The D4 Polyacrylite offers many of Troy Lees' best safety features, including MIPS C2 protection against rotational forces, an EPS impact absorbing liner and an impact resistant ABS (Acrylonitrile Butadiene Styrene) shell. As well, it comes with an adjustable visor that will protect your eyes from flying mud or the sun but can be raised to maximise your visibility if needed.

An impressive 16 vents work to keep you cool as you ride, speeding the air through the front air intake system, then around your head to take away heat. Nonetheless, we all get a bit sweaty while racing, which is why this helmet includes quick dry comfort padding, which is also antimicrobial and anti-odour, so that it will feel great and smell fresh every time you put it on.

Strong, dependable and unmistakeably Troy Lee, the D4 Polyacrylite helmet offers the protection and comfort you need for stunting or dialling in your DH riding technique in the run-up to race day.
