Troy Lee Designs D4 Composite Helmet

The all-new Troy Lee Designs D4 Composite Helmet is stronger and lighter than ever before. It mirrors the D3 in terms of shape and performance, but it emerges with a newfound sense of strength, durability, and utmost protection. An aerospace shell gives the D4 its profile with an ultra-light and equally strong exterior that’s been strategically designed to take a beating without adding bulk. A MIPS C2 protection system works from the inside-out to add an additional layer of defense against rotational forces and sudden impacts mid-ride. Comfort is magnified through the use of copious ventilation channels, power grid mesh panels, and an anti-microbial/anti-odor inner liner—all of which combine to give the D4 Composite a strikingly breathable, fresh, and comfortable fit for every mission. It’s lightweight but it never lacks on puncture-resistance. It’s solid and sturdy but it never compromises comfort. It’s streamlined and versatile with a full-face design that offers maximum coverage for the fastest rides on the toughest trails. Troy Lee Designs’ D4 Composite Helmet has been strategically designed for aggressive performance, keeping up with the best riders in the most technical terrain.
