Troy Lee Designs D4 Polyacrylite Mountain Bike Helmet with MIPS

Expanding the D4 range, the reigning king of BMX and downhill full-face bike helmets, is the Polyacrylite model. This new addition offers the same safety and comfort features as the premium carbon and composite models, but at a more affordable price point. The D4 is considered the most sought-after full-face helmet in the mountain biking community, thanks to details like MIPS C2 protection, an air intake system for ventilation, and an unmatched anatomical fit.

Specifically designed for biking activities such as mountain biking and off-road cycling, the D4 features a Polyacrylite shell, an EPP Collarbone impact system, and chinbar shock pads, all weighing in at a total of 1150 grams. Ventilation is key with 24 vents, including 10 front intake ports, 5 overhead channeling intake vents, and 7 rear exhaust ports.

Comfort and fit are also prioritized with 3 shell sizes, 3 EPS sizes, and 6 total sizes ranging from XS to XXL. The helmet also boasts anatomical, quick-release "3D" cheek pads for a customized fit. For added convenience, the D4 comes with a removable, washable Coolmax-Dri-lex comfort liner and super light D-rings.

With a legacy of 40 years in racing, Troy Lee Designs continues to cater to the needs of the world's fastest racers, ensuring top-quality performance and safety in all their products.
