Troy Lee Designs D4 Polyacrylite MIPS Helmet Charcoal/White
Full-face protection and cooling airflow come together through an advanced Polyacrylite shell paired with a front air intake system that channels ventilation through the helmet. The D4 Polyacrylite Helmet delivers the trusted fit and protection of the D4 platform in a durable construction built for aggressive riding.
Troy Lee Designs equips the D4 Polyacrylite Helmet with the Mips® C2 rotational impact protection system and a Collarbone Suspension System to help manage impact forces. Breakaway visor screws, antimicrobial padding, and quick-release 3D cheek pads support safety, comfort, and an anatomically optimized fit.
Key Features
- Mips® C2 Protection System: Rotational impact protection designed to help reduce forces transferred to the head during angled impacts.
- Polyacrylite Shell Construction: Advanced shell material balances durability and structural protection.
