Troy Lee Designs D4 Helmet

The Polyacrylite model uses a durable, slightly heavier shell material compared to the premium carbon fiber version. While it carries a bit more weight, it offers the same high-level safety features and impact protection at a more accessible price point.

Yes, the D4 Polyacrylite comes equipped with the Mips rotational impact protection system. This is integrated directly into the helmet to help reduce rotational forces on the brain during certain types of angled impacts.

Yes, the anatomical cheek pads are removable and washable. This makes it easy to keep the interior fresh after long days on the trail or at the track.

The expanded polypropylene (EPP) chin bar is designed specifically for energy management. It provides a robust structure that absorbs impact forces in the front of the helmet, which is a critical area for downhill and BMX riders.

The helmet features anatomical cheek pads that can be quickly removed by medical personnel in an emergency. This allows for safer removal of the helmet from a rider's head without putting unnecessary strain on the neck or spine.

While it is engineered specifically for the rigors of downhill and BMX racing, it is also a popular choice for enduro riders who prioritize maximum protection on aggressive stages. Keep in mind that it is a full-face helmet, so it will be warmer and heavier than a standard trail helmet.
