Troy Lee Designs D4 Polyacrylite Helmet

The Polyacrylite shell offers similar impact protection and structural integrity to the carbon version but at a heavier weight and a lower price point. It is an excellent choice for riders who want D4 performance without the premium cost of carbon fiber.

This system is designed to mitigate impact forces that travel from the helmet to your collarbone during a crash. It acts as a buffer to help reduce the risk of clavicle injuries, which are common in high-speed gravity riding.

Yes, the interior padding is fully removable and features anti-microbial properties to help manage sweat and odors. You can easily take it out to wash it after particularly intense or muddy riding sessions.

Yes, it is equipped with the Mips C2 rotational impact protection system. This technology is designed to reduce rotational forces on the brain during certain types of angled impacts.

Yes, the helmet uses breakaway visor screws. These are engineered to snap off during an impact to prevent the visor from snagging on the ground and transferring unnecessary force to your head and neck.

While it is designed primarily for downhill, gravity, and BMX, it features a high-flow ventilation system that keeps air moving. However, because it is a full-face helmet, it will be heavier and warmer than a standard open-face trail helmet.
