Troy Lee Designs D4 Carbon MTB Helmet

Troy Lee Designs D4 Carbon MTB Helmet

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.
