Troy Lee Designs D4 Composite HelmetA classic of the mountain bike world, the Troy Lee Designs D4 Composite Helmet has a well-won reputation for delivering superb levels of comfort, protection and distinctive style. Pull it on and go get your mountain bike thrills in style. No matter where you get your mountain bike thrills, from weekend races on challenging downhills through to racing buddies to the bottom at the local trail centre or bike park, the D4 Composite Cycle Helmet has you covered. Confidence is given a boost thanks to its superb combination of safety features, unrivalled comfort and the usual Troy lee flair for design. 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 outstanding crash 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.MIPS (Multi-directional Impact Protection System) The Mips system is designed to provide added safety for helmets in many accidents. For certain impacts, the Mips system can reduce harmful rotational motion that might otherwise be transferred to the user’s head.Rotational motion is a common cause of concussions in oblique hits to the head. In a crash, the Mips system is designed to move slightly inside the helmet to help redirect forces away from the head.Uncompromised ComfortWith 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.Tough, durable, protective and yet lightweight, the D4 Composite is the ideal full-face helmet for the weekend DH racer and avid mountain bike trail slayer.Features:Aerospace shell design and materials (D4 Composite)MIPS C2 brain protection systemFront air intake system with high flow through polymer centre and powergrid side meshCollarbone suspension systemBreakaway visor screwsX-static® and XT2® Anti-Microbial/anti-order paddingQuick-release contoured 3D cheek pads create an anatomically optimized fitWeight - 1050gCPSC 1203*, CE EN1078*, ASTM F1952 - DH, ASTM 2032 - BMX, *Varies by regional standardsShop all MIPS helmets - Click hereBuy Troy Lee Designs from Chain Reaction Cycles, the World's Largest Online Bike Store.

Built with an aerospace shell design and materials, Troy Lee were able to get the D4 Composite helmet to 1050 grams without sacrificing any strength. MIPS (multi-directional impact protection system) is used to add an additional layer of safety in the event of a fall. For comfort, the D4 Comp routes cooling air through a front air intake system that flows through the polymer centre and power grid side mesh keeping your head cooler during the ride. X-static and XT2 anti-microbial/anti-odor padding keep the inside of the helmet a much nicer place to be.
