The Daytona helmet series has redefined the marriage of technology, safety and artistic design. The Troy Lee Designs D4 Carbon helmet changed the game once again. We were able to strategically increase strength and durability while keeping the overall weight at a premium level. This model also features the integrated MIPS brain protection system, lightweight titanium D-rings, a clavicle suspension system and quick release XT2 3D cheek pads and ionic washable lining.
