D4...Redefining Everything

The Daytona, D2, and D3 series of helmets redefined the marriage between technology, safety, and artistic design. The new Troy Lee Designs D4 Carbon Helmet with MIPS is changing the game again.

Using TeXtreme® Spread Tow carbon fiber reinforcements in the shell of the new TLD D4 Carbon Freedom mountain bike helmet has helped pare down the weight of the full-face helmet by almost 50 grams without sacrificing strength.

Despite the loss in weight, EPS was strategically added to increase strength and durability. Integrated MIPS Brain Protection System designed to reduce rotational motion transferred to the brain from angled impacts to the head. The new TLD D4's package is rounded out with lightweight titanium D-rings, collarbone suspension system and quick release XT2 3D cheek pads, and X-Static washable liner.

Features:

  • MIPS C2 brain protection system-protects against rotational impacts
  • TeXtreme® Spread Tow carbon fiber shell
  • 3 Shell sizes and 3 EPS sizes, 6 total size ranges from XS-XXL
  • 24 total vents: 10 front intake ports, 5 overhead intake vents that channel air on top of your head, and an industry-leading 7 rear exhaust ports
  • Anti-Microbial/Quick Dry XT2® Quick release contoured 3D cheek pads create an anatomically optimized fit. Separately placed X-Static® & XT2® precision fit headliner with 7 anchor points gives you an optimal fit
  • EPP Collarbone impact system; a relief area that reduces the forces in the center lower section of the helmet where shoulder/collarbone impacts have been known to occur
  • Lightest Carbon DH/BMX Race helmet we have ever built at 1000g (+/- 50gm and Size M)
  • Titanium D-Ring fasteners
  • 3-year warranty
  • CPSC 1203*, CE EN1078*, ASTM F1952-DH, ASTM 2032-BMX. *Varies by regional standards
