Troy Lee Designs D4 Composite Slash Helmet (MIPS)

Privateer Perfection

You might race Downhill hard at the weekends or enjoy getting rowdy as often as possible with ride buddies on local MTB trails. Whatever gives you a thrill, you want the confidence to know you can throw yourself down any trail safe in the knowledge your head is covered should you find yourself ejected unceremoniously from your bike. Enter the outstanding D4 Composite Slash Helmet (MIPS).

Keeping weight low but protection and durability high is the aerospace-grade fibreglass composite shell. This wraps around an impact-absorbing EPS foam core - the forces from any crash are absorbed and dissipated by this core, offering superb protection. Meanwhile, breakaway screws prevent the visor from catching on the ground and help prevent neck injuries. Lastly, MIPS (Multi-directional Impact Protection System) provides excellent brain-injury prevention - more on that below.

Sweat-busting Coolness

With this level of protection and head protection, you may think ventilation is compromised. But not a bit of it. Troy Lee have carefully engineered the outer vents and inner channels to work with the headliner so fresh air is free to circulate and keep you cool. Inside the D4 you'll also enjoy the brilliant XT2 washable liner. Lesser helmets will use standard foam liners which after continued use can soon start to feel uncomfortable and even itchy. Not the XT2. This anti-bacterial liner ensures no nasty odours or itchiness, and being washable you'll be able to keep it fresh for every ride.

What is MIPS?

Multi-directional Impact Protection System (MIPS) is a proven system that reduces the rotational forces on the brain when you're involved in a crash. The forces are absorbed and redirected to prevent them from being transmitted to the brain.

MIPS is a Brain Protection System

Rotational motion can cause brain injuries

The low friction layer allows a sliding movement of 10–15 mm, in all directions, reducing rotational motion to the brain during impact

MIPS adds protection

Tough, durable, protective and yet lightweight, the D4 Composite Slash Helmet is the ideal full-face helmet for the weekend DH racer and avid mountain bike trail slayer.
